it depends normally calcium is soft
There are a couple of things that make chalk hard. The calcium in chalk is said to make chalk hard.
In hard water containing calcium chloride dissolved in distilled water, the ions present would be calcium (Ca2+) and chloride (Cl-). The calcium ions come from calcium chloride, while the chloride ions come from the dissociation of calcium chloride in water.
Zinc is considered a hard metal; its hardness is similar to that of Iron.
Gypsum is a Calcium-rich rock that forms when water evaporates. It is commonly found in sedimentary environments and has a soft, white appearance.
Low Calcium Hardness in pool water means that there is low calcium in the water and is considered "soft" and soft water tends to be corrosive. It will etch away and your plaster and any metal object the pool water touches.
Hard water has more calcium than soft water does
The difference is in the name; soft corals have a soft body, with no bony or hard parts. In contrast, hard corals have a hard endoskeleton made of calcium carbonate.
Temporary hard water contains bicarbonates of calcium and magnesium. We can convert it to soft water by boiling or by adding calculated quantity of calcium hydroxide.
Hard water contains bicarbonates of calcium and magnesium or sulphates and chlorides od calcium and magnesium . It can be converted to soft water by boiling or by adding calculated quantity of calcium hydroxide .
Hard water contain sulfates of calcium and magnesium, sometimes chlorides.Soft water contain calcium and magnesium bicarbonates.
Hard water has a significative concentration of soluble calcium or magnesium salts and possible other salts. Soft water is significantly more pure.
Hard water contain calcium bicarbonate, magnesium bicarbonate in temporary hard water and calcium/magnesium sulfate in permanent hard water. Soft water contain doesn't contain these substances or only in very limited concentations.
Calcium is a mineral found in higher concentrations in hard water than in soft water. The presence of calcium and magnesium carbonates and sulfates makes water hard, which can lead to mineral deposits in plumbing systems and appliances. Soft water typically contains lower levels of these minerals due to the filtration or removal of calcium and magnesium ions.
Soft or hard water has to do with the amount of dissolved minerals in water and what those minerals are. "Harder" water has more dissolved minerals (like calcium.)
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.
Calcium is a metal. It is a soft, silvery-white metal that is classified as an alkaline earth metal in the periodic table.
calcium build up. rust. if you use it in your baking ingredients, it wont be as soft
