Chemistry/Analysis of Limestone

 · Place the limestone in a 250 mL beaker. Perform steps 2 and 3 in a fume hood. 2. Obtain 10 mL of 6 M hydrochloric acid (CARE: very corrosive!). Add the hydrochloric acid to the limestone and, using a hot plate which is pre-heated to medium-low heat, heat for 5 minutes or until the bubble-producing reaction ceases.

Limestone | Feedipedia

Calcitic limestone contains 36-38% calcium and can safely be fed free choice (ad lib) mixed with salt. Dolomitic limestone contains at least 5 % magnesium carbonate and should not be used for poultry, but it is as good as calcitic limestone for other animals. Portland and natural cement can be used instead of limestone.

Limestone: Who, What, Why, When, and How?

 · What is Limestone: Limestone is primarily composed of calcium carbonate but many contain small amounts of clay, silt and dolomite. Dolomitic limestones come from natural deposits which contain both calcium and magnesium carbonates. The magnesium content of limestone is especially important where soils are deficient in this essential plant nutrient.
