Vedclass · Answer

(A) The acidic strength of oxides depends on the nature of the element bonded to oxygen. Metallic oxides like $CaO$ and $CuO$ are basic in nature. $CaO$ is a strong base,while $CuO$ is a weaker base compared to $CaO$. $H_2O$ is amphoteric (neutral). $CO_2$ is an acidic oxide because non-metallic oxides are generally acidic. Therefore,the correct order of increasing acidic strength is $CaO < CuO < H_2O < CO_2$.

Oxide	Nature
$a$. $CO$	$i$. Basic
$b$. $BaO$	$ii$. Neutral
$c$. $Al_2O_3$	$iii$. Acidic
$d$. $Cl_2O_7$	$iv$. Amphoteric

Which of the following is the correct order of acidic strength?
