Question

What is the pH of an acidic solution with a hydrogen ion concentration of 2.2 x 10^-3 M?

Answer 1

The pH of an acidic solution is calculated using the formula:

pH = -log[H+]

where [H+] is the hydrogen ion concentration in moles per liter (M). In this case, the hydrogen ion concentration is 2.2 x 10^-3 M.

Now, calculate the pH:

pH = -log(2.2 x 10^-3)

You can use a calculator to find the value:

pH ≈ -(-2.66) ≈ 2.66

So, the pH of the acidic solution with a hydrogen ion concentration of 2.2 x 10^-3 M is approximately 2.66.

Answer 2

2.66

Step-by-step explanation:

To find the pH of an acidic solution with a hydrogen ion concentration ([H+]) of 2.2 x 10^-3 M, you can use the formula for pH:

pH = -log[H+]

Substitute the given concentration:

pH = -log(2.2 x 10^-3)

Now, calculate the pH:

pH ≈ -(-2.66) (rounded to two decimal places)

pH ≈ 2.66

So, the pH of the acidic solution is approximately 2.66.
