Q: 48. Assuming complete dissociation, calculate the pH of the following solutions:

(A)

(B)

(C)

(D)

Answer:

(i) :

Since HCl is completely ionized,

Structure of HCl Completely Ionized

Structure of HCl Completely Ionized

Structure of HCl Completely Ionized

Now,

Hence, the pH of the solution is 2.52

(ii)

Hence, the pH of the solution is 11.70.

(iii) :

Hence, the pH of the solution is 2.69

(iv) :

Now,

Hence, the pH of the solution is
