Calcium bicarbonate is a chemical with the formula C2H2CaO6, and it is one of the major causes of hard water. It is one of the salts of carbonic acid, containing the negative ion HCO3. Calcium bicarbonate typically exist... More »

Calcium carbonate reacts with hydrochloric acid to form calcium chloride, water and carbon dioxide. The reaction between these two compounds requires two parts hydrochloric acid to one part calcium chloride. This reactio... More »

The solubility of elemental calcium in water is unassessable because calcium reacts with liquid water to produce calcium hydroxide in a hydrolysis reaction. The reaction produces hydrogen gas and calcium hydroxide as byp... More »

Chemically, the difference between the two is that hard water contains calcium and magnesium ions, while soft water does not. Soft water is easier to lather with than hard water is. More »

Calcium carbonate is made up of three elements: calcium, carbon and oxygen. This combination is a chemical compound, which is written out as CaCO3. It has one molecule of calcium, one of carbon and three of oxygen. More »

Calcium carbonate is used to raise the levels of calcium in people who don't get enough calcium in their diets. It is also used for adhesives and as part of construction materials such as concrete, asphalt and plaster. I... More »

Sodium bicarbonate, commonly referred to as baking soda, and acetic acid, which is vinegar, combine to create an acid-base chemical reaction. The baking soda serves as the base and the vinegar is the acid. More »
