Question

A buffer solution has a pH of 4.6. Calculate the concentration of H3O+ in the buffer.

Answer 1

0.000025mol/L

Step-by-step explanation:

pH = -log[H3O+]

Here, we know that pH = 4.6 while the concentration of [H30+] is what we are to find. This can be obtained as follows:

4.6 = -log[H30+]

[H3O+] = -Antilog(4.6)

= 0.000025mol/L
