Vedclass · Answer

(A) To determine the acidic strength,we look at the nature of the oxides and the compound:$1$. $CaO$ is a strong basic oxide (alkaline earth metal oxide).$2$. $CuO$ is a basic oxide (transition metal oxide),but less basic than $CaO$.$3$. $H_2O$ is amphoteric/neutral,acting as a very weak acid.$4$. $CO_2$ is an acidic oxide (non-metal oxide) which forms carbonic acid $(H_2CO_3)$ in water.Therefore,the order of increasing acidic strength is: $CaO < CuO < H_2O < CO_2$.

Identify the correct order of acidic strengths of $CO_2, CuO, CaO, H_2O:-$
