What is the hydroxide ion concentration of a solution whose pOH is 6.42?
Your
3.8 x 10-7M
2.6 x 10-7M
2.6 x 10-8 M
3.8 x 10-8 M

Answer : The hydroxide ion concentration of a solution is,

Explanation :

As we know that:

pH : It is defined as the negative logarithm of hydrogen ion concentration.

Mathematically,

Similarly,

pOH : It is defined as the negative logarithm of hydroxide ion concentration.

Mathematically,

Given:

pOH = 6.42

Therefore, the hydroxide ion concentration of a solution is,

2b2t

explanation:

2b2t
