The material can be apure substance, which contains only onechemical component; in this case, the chemical composition corresponds to the relative amounts of the elements constituting the substance. Normally, it can be expressed with a chemical formula. For an example, the chemical formula for wat...

Calcium phosphate and sulfate minerals can achieve equilibrium in hours; aluminum phosphates, carbonates, and most oxides in a matter of days or weeks; and complex aluminosilicates in years. If the soil solution has been in contact with soil minerals for the time necessary to establish equilibrium...
calcium and magnesium ions may be used to replace all or part of the corresponding chloride salts. Suitable, but non-limiting, salts include sulfates, carbonates, phosphates, acetates, lactates, and gluconates. If desired, hydrochloric acid, lactic acid, sodium diacetate or any other suitable ac...
