The hardness of water is calculated by measuring the concentration of calcium and magnesium ions in the water. This is typically done using a titration method with a chelating agent like EDTA. The results are then expressed in terms of calcium carbonate equivalents.
To calculate water hardness in parts per million (ppm), you can use the formula: Hardness in ppm (Hardness in mg/L) x 1.0.
To calculate the formula for water hardness, you can use the formula: Water Hardness (in mg/L) (Calcium concentration in mg/L x 2.497) (Magnesium concentration in mg/L x 4.115). This formula takes into account the concentrations of calcium and magnesium ions in the water to determine the overall hardness.
Magnesium sulfate (MgSo4) does not cause hardness of water.
Boiling water does not affect the hardness of water. Hardness in water is caused by minerals like calcium and magnesium, which remain in the water even after boiling.
Water hardness is typically calculated by measuring the concentration of calcium and magnesium ions in the water. This can be done using a titration method with a chelating agent like EDTA. Factors to consider in the process include the pH of the water, the temperature, and the presence of other ions that may interfere with the titration.

u can chek the hardness by pH scale...lolz

Salt is sometimes used to remove water hardness. Borax and soda are generally used as well to remove water hardness.
Temporary hardness of water: CaHCO3, MgHCO3 Permanent hardness of water: CaSO4, MgSO4
The water supplier can provide you the details on hardness level if you are on municipal water systems, If you are using private water then you can get tested in laboratories. You can even measure it with water hardness testing kits which you need to purchase.

Factors to consider in the process include the pH of the water, the temperature, and the presence of other ions that may interfere with the titration.
To measure permanent hardness by EDTA titration, first add a buffer solution to the water sample to maintain a stable pH. Then, titrate with standardized EDTA solution until the color changes indicating the endpoint. The volume of EDTA required to reach the endpoint can be used to calculate the concentration of the ions causing permanent hardness in the water.
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.
Hardness in water is usually characterised as temporary or permanent. Both are due to the presence of calcium or magnesium ions. If they are present as the hydrogen carbonate, when the water is boiled this is converted to the carbonate which precipitates out as a solid, leaving water which is no longer hard, so this is called temporary hardness. If they are present as the sulfate the solution is unaffected by boiling, and this is called permanent hardness.
