Question: How many moles of potassium hydroxide are needed to neutralize 0.1 moles of hydrochloric acid?

Options:

Correct Answer: 0.1

Solution:

The reaction between KOH and HCl is 1:1. Therefore, 0.1 moles of HCl will require 0.1 moles of KOH.

How many moles of potassium hydroxide are needed to neutralize 0.1 moles of hydrochloric acid?

How many moles of potassium hydroxide are needed to neutralize 0.1 moles of hydrochloric acid?

Step 1: Identify the chemical reaction between potassium hydroxide (KOH) and hydrochloric acid (HCl).
Step 2: Understand that the reaction between KOH and HCl is a 1:1 ratio, meaning one mole of KOH neutralizes one mole of HCl.
Step 3: Determine how many moles of HCl you have, which is given as 0.1 moles.
Step 4: Since the ratio is 1:1, conclude that you will need the same amount of KOH as HCl to neutralize it.
Step 5: Therefore, you will need 0.1 moles of KOH to neutralize 0.1 moles of HCl.

Stoichiometry – Understanding the mole ratio in chemical reactions, specifically the 1:1 ratio between KOH and HCl.
Neutralization Reactions – Recognizing that acids and bases react in a specific ratio to neutralize each other.
