Question

What is the concentration of H+ ions at a pH = 7? mol/L What is the concentration of OH– ions at a pH = 7? mol/L What is the ratio of H+ ions to OH– ions at a pH = 7? :1

Answer 1

Answer: The answer is

=0.0000001

=0.0000001

=1

Explanation: hope this is helpful :)

Answer 2

Answer;

= 0.0000001 mol/L

= 0.0000001 mol/L

= 1:1

Explanation;

What is the concentration of H+ ions at a pH = 7?

The formula for ph is given by:

pH=−log10[H+]

In calculating for the concentration of hydrogen ion, the formula is given by:

[H+]=(10)^(-pH)

Therefore; at pH = 7

[H+]=(10)^(-7)

= 0.0000001 mol/L

What is the concentration of OH– ions at a pH = 7?

pH+pOH=14

7+pOH=14

pOH= 7

[OH-]=(10)^(-pOH)

[OH-]=(10)^(-7)

= 0.0000001 mol/L

What is the ratio of H+ ions to OH– ions at a pH = 7?

1:1
