Calculate the hydrogen ion concentration in a solution of fruit juice having a pH of 4.25.
A) 1.0 x 10^-14 M
B) 5.6 x 10^-5 M
C) 4.0 x 10^-25 M
D) 2.5 x 10^-4 M
E) 5.6 x 10^-4 M

Answer:

The answer is option B

Explanation:

The pH of a solution can be found by using the formula

pH = - log [ H+ ]

To find the hydrogen ion concentration substitute the pH into the above formula and solve for the [ H+ ]

From the question

pH = 4.25

So we have

4.25 = - log [ H+ ]

Find the antilog of both sides

That's

[tex][ H+ ] = {10}^{ - 4.25} [/tex]

We have the final answer as

[tex][ H+ ] = 5.6 \times {10}^{ - 5} \: M[/tex]

Hope this helps you
