Assertion (A): Aqueous solution of ammonium carbonate is basic. Reason (R) : Acidic/basic nature of a salt solution of a salt of weak acid and weak base depends on K_a and K_b value of the acid and the base forming it. |

Answer» Both ASSERTION and Reason are true and Reason is the CORRECT explanation of Assertion. `{:((NH_4)_2CO_3 to , 2overset+NH_4+,CO_3^(2-)),(""2H_2O to, 2OH^(-) + , 2H^+),(,darr,darr),(,NH_4OH,N_2CO_3),(,"WEAK base","weak acid"):}` `K_b` of `NH_4OH gt K_a ` of `H_2CO_3` so solution is BASIC `K_a` of `H_2CO_3 gt K_b` of `NH_4OH` , the solution is ACIDIC. |
