Problem 94P

A 25.0-mL sample of an unknown HClO4 solution requires 45.3 mL of 0.101 M NaOH for complete neutralization. What was the concentration of the unknown HClO4 solution? The neutralization reaction is:

HClO4(aq) + NaOH(aq) → H2O(l) + NaClO4(aq)

Problem 94P

A 25.0-mL sample of an unknown HClO4 solution requires 45.3 mL of 0.101 M NaOH for complete neutralization. What was the concentration of the unknown HClO4 solution? The neutralization reaction is:

HClO4(aq) + NaOH(aq) ? H2O(l) + NaClO4(aq)

Step by step solution

Step 1 of 3

The molarity of the solution is calculated by the following equation;

......(1)

Rearrange the formula (1)

....(2)

From the given,

Molarity = 0.101M

Volume = 45.3 mL = 0.0453L

Substitute the values in the equation (2)
