Question

Metals and non-metals react with oxygen to give oxides at different rates. The oxides formed by metals are basic in nature while oxides formed by non-metals are acidic in nature. The nature of oxides can be determined by tasting the aqueous solution of oxide with litmus paper. (1) Magnesium ribbon on burning in air gives a white powder which when dissolved in water turns red litmus blue. The reason for this change is that……………​

Answer 1

Nonmetals also form covalent oxides, which are usually molecular in character. ... Ionic metal oxides react with water to give hydroxides (compounds containing the OH− ion) and resultant basic solutions, whereas most nonmetal oxides react with water to form acids and resultant acidic solutions (see the table).

Answer 2

Answer:

the red litmus turn to blue because , when red litmus come in contact with basic substance it changes its colour to blue
