No. There is different types of hard water.There is slightly hard, moderately hard, hard and very hard water.And as for soft water it has to have less than a grain of calcium or magnesium. Hard water isn't as useful as soft water.
Because people doesn't same everywhere. it is a rule of nature everything will be change according to human even water.
nope.
always the refractive index of water is same.....
Magnesium sulfate (MgSo4) does not cause hardness of water.
The water cycle will forever go round and round.
Boiling water does not change its hardness. Soft water typically refers to water that has low levels of calcium and magnesium ions. Boiling water may reduce certain impurities like bacteria, but it does not affect water hardness.
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.
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
they would weigh the same everywhere
no, because it their structure is same everywhere
You start by scratching it and seek it's hardness. When you find its hardness, compare it to another mineral with the same hardness. If they look exactly the same, and have the same arrangements of minerals, then they are the exact same mineral.
