Question

in a solution hydroxide ions construction is 1*10 -9mole/l find the ph value of the solutionin a solution ​

Answer 1

pH = -log[H+]

Where [H+] = Hydrogen ion concentration

In this case,

[H+] = 1 × 10^(-2) = 10^(-2)

log{10^(-2)} = -2

-log{10^(-2)} = -(-2) = 2

pH = -log{10^(-2)} = 2

Answer 2

Explanation:

[OH^-] = 10^-9

pOH=9

pH=14-9=5. [pH+pOH=14]
