Question

What is the ph of 0.0080 M HCI

Answer 1

HCl is a strong acid, so we use the following formula:

[H^+] = a × Molarity

= 1 × 0.35 M

= 0.35 M (the concentration of H^+)

pH = - log [H^+]

= - log 3.5×10^-1

= 1 - log 3.5

= 0.456

Step-by-step explanation:

Answer 2

The pH of the solution is 2.10 .

Step-by-step explanation:

The pH gives us an idea of the acidity or basicity of a solution. More precisely, it indicates the concentration of H30 + ions present in said solution. The pH scale ranges from 0 to 14: from 0 to 7 corresponds to acid solutions, 7 neutral solutions and between 7 and 14 basic solutions. It is calculated as:

pH = -log (H30 +)

pH= -log (0.0080)

pH= 2.10
