Answer 1

I want method of preparing of Chromium III sulphate.

**Answer:**

When heated to $1200^{\circ}\mathrm{C}$ chrome dissolved in concentrated sulfuric acid forms Chromium III sulphate:

$$2 \mathrm{Cr} + 6 \mathrm{H_2SO_4} (\text{concentrated}) = \mathrm{Cr_2(SO_4)_3} + 3 \mathrm{SO_2} + 6 \mathrm{H_2O}$$
