What is the pH of the perchloric acid solution if 4.55 L of perchloric acid solution reacted completely with 1.86 g sodium carbonate in a double replacement reaction?

Answer 1

Perchloric acid = HClO₄

Sodium carbonate = Na₂CO₃

Reaction:

2HClO₄ + Na₂CO₃ ==> H₂CO₃ + 2NaClO₄ ==> H₂O + CO₂ + 2NaClO₄

To answer this question, we need to know the concentration of the perchloric acid (HClO4). We are given4.55 L, but we are not provided the concentration. Hence, it is not possible to find moles of HClO4.

Perhaps, you should go back and re-read the question, and then submit it again.
