Sodium hydroxide and perchloric acid react to produce sodium perchlorate and water. How many moles of the acid will react with 1.05 moles of sodium hydroxide?

1.05 moles of HClO₄

Explanation:

To answer the question we need to;

1. Write the equation for the reaction;

The equation for the reaction between sodium hydroxide and perchloric acid is given by;

HClO₄ + NaOH → NaClO₄ + H₂O

2. Determine the mole ratio of NaOH to HClO₄

From the equation;

1 mole of NaOH reacts with 1 mole of HClO₄.

Therefore; the mole ratio of NaOH to HClO₄ is 1 : 1

3. Determine moles of HClO₄ required

Since the mole ratio of NaOH to HClO₄ is 1 : 1

Then, Moles of NaOH = Moles of HClO₄

Therefore;

Moles of HClO₄ = 1.05 moles

We can therefore, conclude that 1.05 moles of HClO₄ are required to react with 1 mole of NaOH.
