(A) Water is a......................oxide.

A mixture of sodium oxide and calcium oxide are dissolved in water and saturated with excess carbon dioxide gas. The resulting solution is ......... It contains :

The standard oxidation potential of water is ......V .

An alkaline earth metal 'M' readily forms water soluble sulphate and water insoluble hydroxide. Its oxide MO is very stable to heat and does not have rock - salt structure. M is

A metal M readily forms its sulphate MSO_(4) which is water soluble. It forms oxide MO which becomes inert on heating. It forms insoluble hydroxide which is soluble in NaOH . The metal M is:

Show by a chemical reaction with water that Na_(2)O is a basic oxide and ClO_(7) is an acidic oxide.

Show by chemical with water that Na_(2) O is a basic oxide and CI_(2)O_(2) is an acidic oxide.

In the presence of water, sulphur is oxidized by ozone to yield
