Question

Identify the correct order of acidic strength of co2 cuo cao h2o

Answer 1

Both CaO and CuO are metallic oxides and hence they are basic oxides. But, Ca is more basic than Cu making CuO to be more acidic than CaO.


H2O is a neutral compound and CO2 is an acidic oxide and is, therefore, more acidic than H2O.


In conclusion, the order of acidic strength is:
CaO (Least acidic)

CuO

H2O

CO2 (Most acidic)

Answer 2

Answer:

Explanation:

Both CaO and CuO are metallic oxides and hence they are basic oxides. But, Ca is more basic than Cu making CuO to be more acidic than CaO.

H2O is a neutral compound and CO2 is an acidic oxide and is, therefore, more acidic than H2O.

In conclusion, the order of acidic strength is:

CaO (Least acidic)

CuO

H2O

CO2 (Most acidic)
