Question

In a certain acidic solution at 25 ∘C, [H+] is 100 times greater than [OH −]. What is the value for [OH −] for the solution?

Answer 1

Answer: The value of $[OH^-]$ for the solution is $10^{-6}M$

Explanation:

To calculate the concentration of hydroxide ion for the solution, we use the equation:

$[H^+]\times [OH^-]=10^{-14}$

We are given:

$[H^+]=100\times [OH^-]$

Putting values in above equation, we get:

$100\times [OH^-]\times [OH^-]=10^{-14}$

$[OH^-]^2=\frac{10^{-14}}{100}$

$[OH^-]=\sqrt{10^{-12}}$

$[OH^-]=10^{-6}M$

Hence, the value of $[OH^-]$ for the solution is $10^{-6}M$
