Question

Aluminum is used for the extraction of chromium from chromic oxide.Explain​

Answer 1

Answer:

Since the Gibbs free energy change is negative, aluminium can reduce chromium oxide. In pyrometallurgy, aluminium is used as a reducing agent in the alumino-thermic process or thermite process to extract chromium and manganese by reduction of their oxides
