b.pH = 4.9
c.pH= 1.4
d.pH= 3.1
e.pH = 14.6
f.pH = 8.0
g.pH = 13.4
h.pH = 6.0

Respuesta :

The pH of a solution with a [H3O+]  is 4.9 .Thus option (b) is true.

What is pH?

pH is defined as negative log of H3O+ ion construction.

The pH can be calculated using formula:

pH = - log [H3O+].

[H3O+] = 7.5 x 10-4 M

pH = - log[7.5 x 10-4M]

pH = 4.9

The pH of a solution with a [H3O+] = 9.4 x 10-7 M = 2.6 = (a)

The pH of a solution with a [H3O+] = 3.7 x 10-14 M = 4.9 = (b)

The pH of a solution with a [H3O+] = 4.2 x 10-2 M = 2.6 = (a)

Thus, the pH of a solution with a [H3O+]  is 4.9 .Thus option (b) is true.
