Calcium,strontium,and barium are all prepared commercially by the same method which is
A)electrolysis of the molten metal oxides.
B)electrolysis of the molten metal halides.
C)chemical reduction of the metal oxides with aluminium.
D)chemical reduction of the metal halides with oxygen.

Question

Quizplus · Accepted Answer

Calcium, strontium, and barium are all highly reactive metals and are prepared commercially by the reduction of their respective metal oxides with aluminium. This is because the reduction of the metal halides with oxygen can be difficult due to their high reactivity, and the electrolysis of the molten metal halides or oxides can be energy-intensive and expensive.
