Pseudo hardness of water refers to the presence of certain dissolved minerals, primarily calcium and magnesium, that affect water's behavior but do not contribute to its actual hardness. This concept is often used to describe situations where water appears hard due to the presence of certain ions, but the hardness is not strong enough to cause scale formation or significant impacts on cleaning and soap efficiency. Pseudo hardness can be influenced by factors like temperature and pH, distinguishing it from true hardness, which is typically measured in terms of calcium carbonate concentration.
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.
Qatar is boarded by water and the Kingdom of Saudi Arabia.
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
Qatar is within the Persian Gulf. It has no natural bodies of fresh water.
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.
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.
To calculate water hardness in parts per million (ppm), you can use the formula: Hardness in ppm (Hardness in mg/L) x 1.0.
There are two ways to help control water hardness: use a packaged water softener or use a mechanical water softening unit. Packaged water softeners are chemicals that help control water hardness.
