The chlorine to ammonia ratio typically used for the formation of monochloramine (NH2Cl) in water treatment is 1:1. This means that one mole of chlorine (Cl2) reacts with one mole of ammonia (NH3) to produce monochloramine. This ratio is important for maintaining effective disinfection in water treatment processes while minimizing the formation of harmful disinfection byproducts.

FAQs
What is the ratio of ammonia to chlorine? The ratio of ammonia (NH3) to chlorine (Cl2) in a chlorination reaction depends on the specific reaction and conditions. In a balanced reaction for the formation of chloramines, the ratio is typically 1 mole of NH3 to 1 mole of Cl2.
How much chlorine is required to react with 1 mg of ammonia? The molar mass of ammonia (NH3) is approximately 17 grams/mol, and the molar mass of chlorine (Cl2) is approximately 71 grams/mol. Assuming 1 mg of ammonia, you would need approximately 4.18 mg of chlorine to react with it.
How do you calculate chloramines? Chloramines are typically formed in a two-step reaction between ammonia and chlorine. The balanced equation is:
NH3 + Cl2 → NH2Cl (Monochloramine) + HCl NH2Cl + Cl2 → NHCl2 (Dichloramine) + HCl NHCl2 + Cl2 → NCl3 (Trichloramine) + HCl
To calculate the amount of chloramines formed, you would need to know the initial concentrations of ammonia and chlorine and the reaction conditions.

Is monochloramine more effective than free chlorine? Monochloramine is often used in water treatment because it has a longer-lasting residual disinfectant effect compared to free chlorine (hypochlorous acid and hypochlorite ions). It can provide more consistent disinfection over time in distribution systems. However, its effectiveness depends on various factors, including water quality and the specific application.
Why should ammonia and chlorine not be mixed? Ammonia and chlorine should not be mixed directly because they can react to form toxic and potentially dangerous chloramines. These chloramines can be harmful to health and should be handled with caution. Mixing should only occur in controlled environments and as part of water treatment processes.
Can you mix ammonium and chlorine? Ammonium ions (NH4+) and chlorine ions (Cl-) can be mixed safely in water without the immediate formation of chloramines. However, if chlorine (Cl2) is introduced to the solution, it can react with ammonia (NH3) to form chloramines.
Does chlorine reduce ammonia? Chlorine can react with ammonia to form chloramines, but it may not completely reduce ammonia levels. The effectiveness of chlorine in reducing ammonia depends on factors like chlorine dosage, contact time, and water quality.
How do you find the ratio of ammonia? The ratio of ammonia can be found by comparing the number of moles of ammonia to the number of moles of other substances in a chemical reaction. The coefficients in the balanced chemical equation indicate the mole ratios.
How do you make a 25% ammonia solution? To make a 25% ammonia solution, you would need to dilute concentrated ammonia (usually 28-30% ammonia) with an appropriate amount of water. The exact dilution ratio depends on the concentration of the concentrated ammonia solution.

How much chlorine does it take to raise 1 ppm? The amount of chlorine required to raise the concentration of chlorine by 1 ppm (parts per million) in a given volume of water depends on the volume of water being treated. It is typically calculated using the formula:
Chlorine (in pounds) = (Desired increase in ppm) x (Water volume in gallons) / 10,000
How do you calculate chemical dosing rate? The chemical dosing rate is calculated based on the specific chemical being used, water volume, desired concentration, and other factors. The formula for dosing rate varies depending on the chemical and application, so it should be determined based on the specific situation and guidelines provided by experts or regulatory agencies.
What is the acceptable and permissible limit of chlorine? The acceptable and permissible limit of chlorine in water depends on the intended use of the water and local regulations. In drinking water, the acceptable residual chlorine levels are typically in the range of 0.2 to 4.0 ppm.
How much chlorine do I need for 1000 gallons? The amount of chlorine needed for 1000 gallons of water depends on the desired chlorine concentration and the current chlorine level. To calculate the amount needed to raise the concentration by a certain amount, you can use the formula mentioned earlier for raising chlorine by 1 ppm and adjust it for your specific target.

Combined chlorine is the chlorine that has reacted with ammonia or other organic materials and is no longer effective as a disinfectant.
What is the ratio of chlorine and water for cleaning? The ratio of chlorine and water for cleaning purposes can vary widely depending on the cleaning task, the type of chlorine product (e.g., bleach), and safety guidelines. Always follow the manufacturer’s instructions for diluting chlorine products for cleaning.
What determines the amount of chlorine to use for disinfection? The amount of chlorine to use for disinfection is determined by factors such as water volume, desired chlorine concentration, contact time, water quality, and regulatory guidelines. Detailed calculations and considerations are typically required for effective disinfection.
What percentage of chlorine is used for water treatment? The percentage of chlorine used for water treatment can vary, but it is often in the form of sodium hypochlorite (bleach) with a chlorine content of around 10-15%. Gas chlorine may have a higher concentration, typically around 100%.

How long do chloramines last? The persistence of chloramines in water depends on various factors, including temperature, pH, and the presence of other chemicals. Monochloramine, for example, can have a longer residual disinfection effect compared to free chlorine and may last longer in distribution systems.
What are the dangers of monochloramine? Monochloramine is generally considered less harmful than some other chloramine compounds, but it can still pose health risks at high concentrations. Inhaling or ingesting monochloramine can irritate the respiratory and digestive systems. It’s important to handle and store monochloramine safely.
What are the three detractors of chlorine effectiveness? The three main detractors of chlorine effectiveness are:
- High organic matter: Chlorine can react with organic compounds in water to form disinfection byproducts and reduce its effectiveness.
- High pH: Chlorine is less effective at higher pH levels.
- Long contact times: If water has long contact times with chlorine before reaching the point of use, its disinfection effectiveness may decrease.
What is one of the major disadvantages of using chloramines as an alternative to free chlorine? One major disadvantage of using chloramines as an alternative to free chlorine is their potential to produce objectionable tastes and odors in water. Chloramines can create off-flavors and odors that some people find unpleasant.

What causes high ammonia in a pool? High ammonia levels in a pool can be caused by several factors, including the introduction of ammonia-containing substances (e.g., urine), organic debris, or the breakdown of chloramines. High ammonia levels can lead to chloramine formation and pool water problems.
What are the 4 methods of chlorination? The four main methods of chlorination are:

- Electrochlorination: The use of electricity to generate chlorine on-site from salt or brine solutions.
Does boiling water get rid of chlorine and ammonia? Boiling water can help to remove chlorine, but it does not effectively remove ammonia. Ammonia is more volatile than chlorine, so it may escape into the air when water is boiled. To remove ammonia, other methods such as aeration or chemical treatment may be necessary.
What is the simplest ratio of ammonia? The simplest ratio of ammonia (NH3) is NH3 itself, indicating one molecule of ammonia consisting of one nitrogen atom and three hydrogen atoms.
What is the dilution ratio for ammonia? The dilution ratio for ammonia depends on the starting concentration and the desired concentration. For example, to dilute a 10% ammonia solution to a 5% solution, you would mix equal volumes of the 10% solution and water (1:1 dilution).
Why is ammonia ratio 14:3? The ratio 14:3 is often used to represent the atomic composition of ammonia (NH3). It indicates that one molecule of ammonia contains one nitrogen atom (atomic number 7) and three hydrogen atoms (atomic number 1).
