Question

if the concentration of OH is
${10}^{ - 9}$M find the pH​

Answer 1

Then the ph is 5

ph is concentration is depend on H+ ion

so the total ph = 14

The ph of OH - = 9

so 14 - 9 = 5

Thanks!!!!!

Answer 2

HEY MATE.....

WE KNOW

pH depends upon the negative value of exponent of 10.

i.e. Concentration of H+ ions = neg. Value of exponent of 10.

H+ ions = 9

Total pH=14

So, concentration of OH-ions = 14-9=5
