`{:("Oxalic acid ",pK_(1)),("Molonic acid",pK_(2)),("Heptanedioic acid ",pK_(3)):}`
Where `pK_(1),pK_(2),pK_(3)` are first ionization constants. Correct order is :

{:("Oxalic acid",pK_1),("Malonic acid",pK_2),("Heptanedioic acid",pK_3):} where pK_1,pK_2 ,pK_3 are first ionization constants. Correct order is :

The pK_(a)of an acid having ionisation constant 1 xx 10^(-3) is

Correct order of pK_(a) value of

Correct order of pK_(a) value of

Determine pK_(a)(H_(2)O)+pK_(a)(H_(3)O) .

If K_(a) and K_(b) are the dissociation constants of weak acid and its conjugate base , pK_(a) + pK_(b)

If K_(a) and K_(b) are the dissociation constants of weak acid and its conjugate base , pK_(a) + pK_(b)

You are asked to prepare a 100 mL buffer solution of pH=5.0. for this purpose, you are supplied with acetic acid (pK_(a)=4.74) , benzoic acid (pK_(a)=4.20) , formic acid (pK_(a)=3.75) and their sodium salts. Which one of the acids will you use to prepare the most effective buffer?

pK_(a) of chloroacetic acid is lower than pK_(a) of acetic acid. Why?
