Find the pH in which the hydrogen ion,H± concentration is 0.395×moldm-³

Answer 1

We can use the formula:

pH = -log[H+]

where [H+] is the hydrogen ion concentration in mol/dm³.

First, let's convert the concentration to mol/dm³:

0.395 × mol/dm³

Next, we can plug this value into the pH formula:

pH = -log (0.395)

Using a calculator, we get:

pH = 0.403

Therefore, the pH at which the hydrogen ion concentration is 0.395 mol/dm³ is approximately 0.403.
