Question

Sulphides ores are converted to oxides before reduction. This is explained on the basis of which of the following?

• A. Sulphides cannot be reduced easily while oxides can be reduced easily.
• B. Sulphides decompose on reduction hence they are fixed converted to oxides.
• C. Sulphide ores have higher melting points than oxides.
• D. Oxides are more stable than sulphides hence easy to reduce.

Answer 1

The correct option is A Sulphides cannot be reduced easily while oxides can be reduced easily.

Sulphides ores are converted to oxides before reduction because sulphides cannot be reduced easily while oxides can be reduced easily.
