Yes, is correct.
YES, it's is the calcium that makes the water "hard". That is why you use a cleaner that has a calcium remover in it to get those hard water stains off.
Forms of Calcium is what makes hard water hard
The presence of calcium and magnesium salts in the form of hydrogencarbonate, chloride and sulphate in water makes water 'hard'. Hard water does not give lather with soap. Whereas, water free from souluble salts of calcium and magnesium is called soft water. It gives lather with soap. And also hard water forms scum(precipitate) with soap, therefore unsutable for laundry but soft water does not form scum.
Hardness of water pretains to the concentration of minerals and other trace elements in your local water supply. Well water-such in my area is "very hard"-meaning it contains a large amount of iron and other minerals-when boiled down in a pot of the water on your stove-it will leave a deposit on the pan once the water has boiled away. A water softener helps filter out these particles.
Hard water contains calcium and magnesium salts. Therefore, in hard water, soaps get precipitated as calcium and magnesium soaps which being insoluble stick to the clothes as gummy mass.
true
Some water is called ''hard'' water because, of all the deposits in the water.

Calcium and iron deposits within the water are harmless and often colorless unless the iron content is large (think rust color). These two elements are creators of 'hard water'.
Typicall water hardness is caused from calcium and magnesium compounds dissolved in the water. The term "hard water" is used to describe water that has a high mineral content, usually calcium and magnesium in the form of carbonates, but may include several other metals as well as bicarbonates and sulfates, (water with a low mineral content is known as soft water). A high enough concentration of these metals in your water can cause white lime scales on surfaces which the water comes into contact with. Total water 'hardness' is reported as ppm w/v (or mg/L) of calcium carbonate (CaCO3). Water hardness usually measures the total concentration of calcium and magnesium, the two most common metal ions, although in some locations around the world iron, aluminium, and manganese may also be present at elevated levels. Calcium usually enters the water as either calcium carbonate (CaCO3), from limestone or chalk, or from mineral deposits of calcium sulfate (CaSO4).
High mineral content (calcium salts).

Hard water contain calcium and magenesium carbonates.
Dissolved minerals in the water. In most cases it is better to water your garden with hard water instead of treated water. The plants typically like the minerals found in hard water.

Nearly all sodium salts are soluble in water. Most calcium salts aren't. calcium salts of the same fatty acids that make up potassium and sodium soaps are not water soluble. Dissolved calcium and magnesium are the two most common minerals that make water "hard." The degree of hardness becomes greater as the calcium and magnesium content increases. Bathing with soap in hard water leaves a film of sticky soap curd on the skin
