Question

The correct order of acidic strength : (A) Cl 2 O 7> SO 2> P 4 O 10 (B) K 2 O > CaO > MgO (C) CO 2> N 2 O 5> SO 3 (D) Na 2 O > MgO > Al 2 O 3

Tardigrade Admin · Accepted Answer

Acidic character of oxide propto Non-metallic nature of element. Non-metallic character increases along the period. Hence order of acidic character is Cl 2 O 7> SO 2> P 4 O 10

Q. The correct order of acidic strength :

$C l_{2} O_{7} > S O_{2} > P_{4} O_{10}$

$K_{2} O > C a O > M g O$

$C O_{2} > N_{2} O_{5} > S O_{3}$

$N a_{2} O > M g O > A l_{2} O_{3}$

Acidic character of oxide $\propto$ Non-metallic nature of element.
Non-metallic character increases along the period.
Hence order of acidic character is $C l_{2} O_{7} > S O_{2} > P_{4} O_{10}$

Q. The correct order of acidic strength :

Cl2​O7​>SO2​>P4​O10​

K2​O>CaO>MgO

CO2​>N2​O5​>SO3​

Na2​O>MgO>Al2​O3​

Acidic character of oxide ∝ Non-metallic nature of element. Non-metallic character increases along the period. Hence order of acidic character is Cl2​O7​>SO2​>P4​O10​

$C l_{2} O_{7} > S O_{2} > P_{4} O_{10}$

$K_{2} O > C a O > M g O$

$C O_{2} > N_{2} O_{5} > S O_{3}$

$N a_{2} O > M g O > A l_{2} O_{3}$

Acidic character of oxide $\propto$ Non-metallic nature of element.
Non-metallic character increases along the period.
Hence order of acidic character is $C l_{2} O_{7} > S O_{2} > P_{4} O_{10}$
