Q1:

If pH value of a solution is 8, then its pOH value will be

A 6

B 1

C 7

D 10

ANS:A - 6

To find the pOH value from the pH value, you can use the relation between pH, pOH, and the ion product of water (𝐾𝑤Kw​): pH+pOH=14pH+pOH=14 Given that the pH value of the solution is 8, we can find the pOH value using this equation: pOH=14−pHpOH=14−pH pOH=14−8=6pOH=14−8=6 So, if the pH value of a solution is 8, then its pOH value will be 6. Therefore, the correct option is 6.
