Question

Solution (1) , which has pH of 4 is added to solution (2) until the mixture has pH of 7.
(a) what can you say about solution (1)
(b) what can you say about solution (2)
(c) what can you say about the mixture of 1 and 2

Answer 1

Explanation:

(a):

As solution 1 has pH 4 it is acidic in nature

(c):

As mixture has pH=7 it is neutral in nature

(b):

As solution 1 and solution 2 gives a mixture of pH=7 and also, solution 1 is acidic,

hence,for mixture of pH=7 it becomes compulsory for solution 2 to be of basic nature

Therefore,we can say that the solution 2 will have a pH>7
