<u>Answer:</u> The pH of the solution is 13.0
<u>Explanation:</u>
To calculate the molarity of solution, we use the equation:
Given mass of KOH = 716. mg = 0.716 g (Conversion factor: 1 g = 1000 mg)
Molar mass of KOH = 56 g/mol
Volume of solution = 130 mL
Putting values in above equation, we get:
1 mole of KOH produces 1 mole of hydroxide ions and 1 mole of potassium ions
- To calculate hydroxide ion concentration of the solution, we use the equation:
We are given:
[tex[[OH^-]=0.098M[/tex]
Putting values in above equation, we get:
To calculate the pH of the solution, we use the equation:
pOH + pH = 14
So, pH = 14 - 1.00 = 13.0
Hence, the pH of the solution is 13.0
