Answer: The salt which has the highest pH is [tex]CH_3COONa[/tex]
Explanation: Salts are formed by the reaction of acid and base. General equation for the generation of salt is given by:
[tex]HX+BOH\rightarrow BX+H_2O[/tex]
The given salts are formed from the reaction of acids and bases.
1) [tex]K_2SO_4[/tex]
This is a salt formed by the reaction of strong base (KOH) and strong acid [tex](H_2SO_4)[/tex] . So, this salt is a neutral salt.
[tex]H_2SO_4+2KOH\rightarrow K_2SO_4+2H_2O[/tex]
2) [tex]CuSO_4[/tex]
This is a salt which is formed by the reaction of weak base [tex](Cu(OH)_2)[/tex] and strong acid [tex](H_2SO_4)[/tex]. So, this salt is an acidic salt.
[tex]H_2SO_4+Cu(OH)_2\rightarrow CuSO_4+2H_2O[/tex]
3) [tex]NH_4Cl[/tex]
This is a salt which is formed by the reaction of weak base [tex](NH_3)[/tex] and strong acid (HCl). So, this salt is an acidic salt.
[tex]HCl+NH_3\rightarrow NH_4Cl[/tex]
4) [tex]CH_3COONa[/tex]
This is a salt which is formed by the reaction of strong base (NaOH) and weak acid [tex](CH_3COOH)[/tex]. So, this salt is a basic salt.
[tex]CH_3COOH+NaOH\rightarrow CH_3COONa+H_2O[/tex]
Now, we have to find the salt which has the highest pH value.
Highest pH value means that the salt must be basic in nature and from the given salts, only [tex]CH_3COONa[/tex] is basic salt. Hence, this salt has the highest pH value.
