and 5 are mixed in a vessel. What will be the H+
ion concentration in the mixture?
[AIPMT (Prelims)-2008]
(1) 1.11 * 10-3 M (2) 1.11 x 10-4 M
(3) 3.7 x 10-4 M
(4) 3.7 x 10-3 M​

Answer 1

Answer:

Solution:

Let the volume of each acid =

pH of first, second and third acids = 3, 4 and 5 respectively

of first acid

of second acid

of third acid
