Non-metallic oxides are acidic and metallic oxides are basic. An increase in metallic (i.e., electropositive) character increases the basic nature of the oxide and an increase in non-metallic (i.e., electronegative) character increases the acidic nature of the oxide. Hence, the correct order is CaO < CuO < H2O < CO2.

Q. Identify the correct order of acidic strength of $C O_{2} C u O, C a O, H_{2} O$

$C a O < C u O < H_{2} O < C O_{2}$

$H_{2} O < C u O < C a O < C O_{2}$

$C a O < H_{2} O < C u O < C O_{2}$

$H_{2} O < C O_{2} < C a O < C u O$

Q. Identify the correct order of acidic strength of CO2​CuO,CaO,H2​O

CaO<CuO<H2​O<CO2​

H2​O<CuO<CaO<CO2​

CaO<H2​O<CuO<CO2​

H2​O<CO2​<CaO<CuO

Q. Identify the correct order of acidic strength of $C O_{2} C u O, C a O, H_{2} O$

$C a O < C u O < H_{2} O < C O_{2}$

$H_{2} O < C u O < C a O < C O_{2}$

$C a O < H_{2} O < C u O < C O_{2}$

$H_{2} O < C O_{2} < C a O < C u O$
