Question

(B) $Li_2O$ and $K_2O$ are basic oxides that react with water to form $OH^{-}$ ions ($Li_2O + H_2O \rightarrow 2LiOH$; $K_2O + H_2O \rightarrow 2KOH$)

Vedclass · Accepted Answer

$SO_3$

Vedclass · Answer

(B) $Li_2O$ and $K_2O$ are basic oxides that react with water to form $OH^{-}$ ions ($Li_2O + H_2O \rightarrow 2LiOH$; $K_2O + H_2O \rightarrow 2KOH$).$Fe_2O_3$ is an amphoteric oxide that is practically insoluble in water.$SO_3$ is an acidic oxide that reacts with water to form $H_2SO_4$,which provides $H^{+}$ ions,not $OH^{-}$ ions.Since the question asks for an oxide that does not produce $OH^{-}$ ions,$SO_3$ is the correct answer.

Which of the following oxides will not give $OH^{-}$ ions in aqueous solution?
