Apparatus Used In Determining Calcium Carbonate In Limestone

This invention concerns a process and equipment for producing precipitated calcium carbonate. According to the process, limestone is burnt at a high temperature to form calcium oxide and, thereafter, calcium carbonate is formed from calcium oxide in the presence of water and carbonate ions and the formed calcium carbonate is recovered

The acid test is used to determine the amount of calcium carbonate and type of lime present in the limestone. The procedure of acid test is as follows. A teaspoon of powdered lime is taken in the test tube and 10 ml of dilute hydrochloric acid is added to it. Substances are stirred thoroughly and kept the mix in a safe place for 24 hours

Calcium carbonate. Three types of calcium carbonate-containing rock are excavated and used by industry. They are limestone, chalk and dolomite. Limestone and chalk are both forms of calcium carbonate and dolomite is a mixture of calcium and magnesium carbonates. All have impurities such as clay but some rocks are over 97% pure

Scope. 1.1 This test method covers the quantitative determination of the calcium carbonate (CaCO3) content of soils. It is a gasometric method that utilizes a simple portable apparatus. The test method is quickly performed for soils containing calcium carbonate. Note 1-The presence of dolomite CaMg (CO3)2 and reducing minerals such as sulfide

2. Use the balanced equation to work out the ratio of CaCO3: CO2 and therefore the number of moles of CaCO3 used. 3. Calculate the mass of CaCO3 used (by doing moles x molecular mass found from periodic table) 4. Calculate the percentage of CaCO3 by doing (mass of CaCO3 from step 3)/ (mass of limestone sample) x 100%

can determine the amount of calcium carbonate in a sample of limestone. The carbon dioxide produced in Step 2 could only have come from the carbonic acid produced in Reaction 1. This allows us to relate the amount of carbon dioxide produced back to the original calcium carbonate (Reaction 3). We can also quantify the calcium carbonate by deter-mining how much calcium ion is present in the
