<u>Answer:</u> The pH of the solution is 1.41
<u>Explanation:</u>
To calculate the molarity of solution, we use the equation:
Given mass of perchloric acid = 581.1 mg = 0.5811 g (Conversion factor: 1 g = 1000 mg)
Molar mass of perchloric acid = 100.5 g/mol
Volume of solution = 150 mL
Putting values in above equation, we get:
1 mole of perchloric acid produces 1 mole of ions and 1 mole of
ions
To calculate the pH of the solution, we use the equation:
We are given:
Putting values in above equation, we get:
Hence, the pH of the solution is 1.41
