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

= 0.0000001 mol/L  

= 0.0000001 mol/L  

= 1:1

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

The answer is  

=0.0000001

=0.0000001

=1
