The following results were obtained for the determination of calcium in a NIST limestone sample: %CaO = 50.32, 50.23, 50.39, 50.20, and 50.43. Five gross samples were then obtained for a carload of limestone. The average percent CaO values for the gross samples were found to be 49.48, 50.10, 49.63, 49.88, and 50.47. Calculate the relative standard deviation associated with the sampling step. Relative standard deviation =

An impure sample of calcium sulphate (CaSO4.2H2O) was analyzed by gravimetric analysis of calcium. A (4.9000x10^-1) gram sample was dissolved in water and the calcium was precipitated, filtered  and   weighed   as   Ca3(PO4)2.   A (2.31x10^-1) gram precipitate was obtained. Calculate the percent by mass of calcium in the sample. [Answer in 3 significant figure]

A sample of limestone and other soil materials was heated, and the limestone decomposed to give calcium oxide and carbon dioxide. CaCO3(s) → CaO(s) + CO2(g) A 6.498 g sample of limestone-containing material gave 2.44 g of CO2, in addition to CaO, after being heated at a high temperature. What was the mass percent of CaCO3 in the original sample? ___%

The questions are for an experiment called Gravimetric Determination of Nickel in An Unknown Solution.Thank you for your time and work! 1) What is the importance of pH control in the determination of nickel by gravimetry? 2)Why do we perform chloride test? I know that we used AgNO3. 3)Write the chelation reaction between nickel and DMG and how does the chelation reaction occur? Explain.

A river flows on a bedrock composed primarily of limestone (calcium carbonate – CaCO3), which partially dissolves in water into calcium (Ca2+) and carbonate (CO32-) ions. The equilibrium concentration of Ca2+ in the water is measured at 1.7 mg/L. The solubility product of calcium carbonate, Ks = 2.8 10-9. Based on these data, calculate the equilibrium concentration of CO32- (in mg/L) in the water (write calculation details).

A plant makes liquid carbon dioxide by treating a limestone with commercial sulfuric acid. The limestone analyzes 65.8% calcium carbonate, 25.7% magnesium carbonate and the rest silica. The acid used was 89.5% sulfuric acid with rest being water. Calculate the pounds of acid required per ton of limestone treated.

Limestone consists mainly of the mineral calcite, CaCO3. The carbonate content of 0.5426 g of powdered limestone was measured by suspending the powder in water, adding 10.00 mL of 1.360 M HCl, and heating to dissolve the solid and expel CO2. CaCO3(s) + 2 H + → Ca2+ + CO2↑ + H2O Calcium carbonate FM 100.087 The excess acid required 39.59 mL of 0.1039 M NaOH for complete titration to a phenolphthalein end point. Find the weight percent of calcite...
