Match the following with their `K_(a)` values
`{:("Benzoic acid",4.2xx10^(-5)),(p"-nitrobenzoic acid",6.4xx10^(-5)),(p"-chlorobenzoic acid",6.4xx10^(-5)),(p"-methylbenzoic acid",36.2xx10^(-5)),(p"-methorybenzoic acid",10.2xx10^(-5)):}`

Dissociation constants of benzoic acid, p-nitrobenzoic acid and p-hydroxybenzoic acid are 6.3xx10^(-5) , 36xx10^(-5)" and "2.5xx10^(-5) respectively. Explain.

The values of ionisation constants for some pairs of acids and bases are given which of them is stronger ? (a) Acetic acid (K_(a) =1.8 xx 10^(5)), boric acid (K_(a) =5,8 xx 10^(-10)) (b) Hydrofluoric acid (K_(a)= 6.7 xx 10^(-4)), benzoic acid (K_(a) =6.3 xx 10^(-5)) (c) Ammonium hydroxide (K_(b) =1.8 xx 10^(-5)) Magensium hydroxide (K_(b) =8.1 xx 10^(-3))

Assertion : Benzoic acid is stronger acid than acetic acid. Reason : K_(a) for benzoic acid is 6.5xx10^(-5) and for acetic acid is 1.74xx10^(-5) .

Calculate the pH of 0.2M sodium butyrate, (K_(a) for butyric acid is 2.0xx10^(-5))

The [H^(+)] of a resulting solution that is 0.01 M acetic acid (K_(a)=1.8xx10^(-5)) and 0.01 M in benzoic acid (K_(a)=6.3xx10^(-5)) :

Calculate the pH of a 0.01 M solution of benzoic acid, the K_a being 7.3xx10^(-5)

What concentration of dichloroacetic acid gives [H^(+)]=8.5xx10^(-3)M ? ("Given": K_(a)"of acid" = 5.0xx10^(-2)) .

K_(a) for formic acid and acetic acid are 2.1xx10^(-4) and 1.1xx10^(-5) respectively. The relative strength of acids is:
