The pOH of a solution is 5.70. The correct option is C; 2.5 x 10-7 is the hydroxide ion concentration.
What is the pOH of the solution?
The pOH of the solution is the negative logarithm of hydroxide ions concentration in a solution. The lower the value of pOH more alkaline will be the solution.
Mathematically written as:
pOH = - Log[OH-]
The sum of ph and pOH is equal to 14.
pH + pOH = 14
The pOH of a solution is 5.70.
pOH = - Log[OH-]
5.70 = - Log[OH-]
[OH-] = 2.5 x 10-7 is the hydroxide ion concentration.
The solution has a pH value of more than 7 which means that it is base.
