Calculate the ph of 0.05M ba(OH)2 aqueous solution
Answers
[OH-] = N = 2×0.05 = 0.1
pOH = -log[OH-] = -log(0.1) = 1
PH = 14-pOH = 14-1 = 13
The pH of 0.05M aqueous solution is 13.
Given:
Molarity of the solution = 0.05M
To find:
pH of the solution = ?
Formula to be used:
pOH = -log()
pH = 14 - pOH
Calculation:
In , 2 hydroxide ions are present.
∴ 0.05 M = []
[] = 2 ×0.05 = 0.1M
∴pOH = -log() = -log(0.1) = 1
Substituting the obtained value in the following formula it gives
pH = 14 - pOH
pH = 14 - 1
pH = 13
Conclusion:
The pH of 0.05M aqueous solution is calculated as 13.
