An oxide solution of which of the following elements will turn blue litmus red?
The element name are not visible in question.
The oxides of non-metal form acid with water. Acid turns blue litmus to red. So, oxide solution of non-metals turns blue litmus to red.
For example carbon is non-metal. Its oxide carbon-dioxide will form carbonic acid with water. The solution turns blue litmus paper red.
CO2 + H2O H2CO3
