A sample of green crystals of nickel (II) sulphate heptahydrate was heated carefully to produce the bluish-green nickel (II) sulphate hexahydrate. What are the formulas of the hydrates? If `8.753 g` of the heptahydrate produces `8.192 g` of the hexahydrate, how many grams of anhydrous nickel (II) sulphate could be obtained?

Text Solution

Verified by Experts

The correct Answer is:
`4.826 g`

A student performed an experiment to determine the ratio of H_(2)O to CuSO_(4) in a sample of hydrated copper (II) sulphate by heating it to drive off the water and weighing the solid before and after heating. The formula obtained experimentally was CuSO_(4).45H_(2)O but the accepted formula is CuSO_(4).5H_(2)O . which error best accounts for the difference in results?
