Why pH is 10 for finding the hardness of water .something related to protonation?
A pH of 10 is often used when testing water hardness because it ensures that all carbonates and bicarbonates present in the water are fully ionized, allowing for accurate measurement of the total hardness. At this pH, the calcium and magnesium ions in the water form insoluble precipitates, which can be quantified to determine the hardness level. The high pH also helps to minimize interference from other ions in the water on the hardness measurement.
What is the meaning of total hardness?
Total hardness refers to the overall concentration of calcium and magnesium ions in water. These ions can create issues such as scale buildup in pipes and appliances. Total hardness is often measured in parts per million (ppm) or milligrams per liter (mg/L).
What is difference between carbonate and noncarbonate hardness?
Carbonate hardness is the measure of hard ions associated with carbonate and bicarbonate anions contained in the water.Noncarbonate hardness is the portion of total hardness in water that is not produced by carbonates, but primarily by sulfate anions.
What is the average hardness of a bottle of water?
The hardness of bottled water can vary widely depending on the source. Typically, bottled water has a low to moderate level of hardness, with most falling within the range of 20-100 mg/L of calcium carbonate equivalents. It's best to check the specific water quality report provided by the bottling company for accurate hardness levels.

How do you calculate the total hardness of a substance?
To calculate the total hardness of a substance, you add the concentrations of calcium and magnesium ions in the substance. This is typically measured in milligrams per liter (mg/L) or parts per million (ppm).
How do you raise the total hardness in pool?
Oh, dude, raising the total hardness in a pool is like adding calcium hardness increaser. You know, it's like giving your pool a little boost of calcium to make it feel all fancy and stuff. Just follow the instructions on the product, and your pool will be harder than a rock in no time.
Why buffer ammonia is used in water total hardness test?
Buffer ammonia is used in water total hardness tests to maintain a stable pH level during the titration process. The presence of ammonia helps prevent fluctuations in pH that could affect the accuracy of the hardness test results.
A corrosion technologist pipetted a 100 ml hard water sample and titrated it with 37.64 ml of 0.01 m edta solution for a total hardness endpoint and 29.32 ml of 0.01 m edta solution for a calcium?
The total hardness of the water sample is calculated as 37.64 ml of 0.01 M EDTA solution. The calcium hardness is calculated as the difference between the total hardness and the magnesium hardness, which is 29.32 ml of 0.01 M EDTA solution. It's important to conduct proper titration techniques to ensure accurate results for water quality assessment.
Why is ammonia-sodium chloride buffer solution is added in the determination of total hardness of water?
Ammonia-sodium chloride buffer solution is added in the determination of total hardness of water to prevent interference from other ions that may be present in the water sample. It helps to maintain a constant pH level, ensuring the validity of the hardness test results. Additionally, the buffer solution can help stabilize the complexation reactions between the calcium and magnesium ions in the water sample with the chelating reagent used in the hardness test.
What should the KH be in a freshwater tank?
The hardness of your water would depend on the species of fish you intend to keep. African Cichlids need hard water with a very high GH/KH (total hardness) but fish from the Amazon need soft water with very low GH/KH (total hardness). I would advise you to always independently research what water parameters are required for whatever species you wish to keep.
What is EDTA titration of Water?
It one of the titrations method to determine the permanent and temporary hardness of water. Procedure; step 1: standardise the edta solution step 2: titrate against the hard water mixed with ebt until the colour changes from wine red to blue. Then we can caluclate the normality using the formula (n1) *(v1)=(n2)*(v2). Posted by Krishna kanth yenumula.
