Question

A mixture of magnesium chloride and magnesium sulphate is known to contain 0.6 moles of chloride ion and 0.2 moles of sulphate ions. For quantitative estimation of Mg, above mixture is treated with set of reagents to form Mg₂P₂O₇ produced is:

A. 0.5
B. 0.25
C. 0.8
D. 0.7

Answer 1

The correct answer is C.

In this problem, we are given that the mixture of magnesium chloride and magnesium sulphate is known to contain 0.6 moles of chloride ions and 0.2 moles of sulphate ions.

For quantitative estimation of Mg, the mixture is treated with a set of reagents, resulting in the formation of Mg2P2O7. Based on the information given and the balanced chemical equation for forming Mg2P2O7, the moles of phosphoric acid (H3PO4) required is 0.8 moles, which corresponds to answer C.
