Understanding Titration and Its Importance in Chemistry
Titration is a laboratory method used to analyze the concentration of an unknown solution by reacting it with a solution of known concentration. This process involves adding a titrant from a burette to a analyte until the reaction reaches its endpoint, often indicated by a color change using an indicator.
Why is mastering titration crucial?
- It helps determine unknown concentrations precisely.
- It is essential in various industries, including pharmaceuticals, environmental testing, and food safety.
- It strengthens understanding of acid-base reactions, redox reactions, and other chemical processes.

Sample Titration Questions with Answers (For Practice)
Including practice questions with step-by-step solutions is an effective way to learn. Here are a few examples:
Question 1:
Calculate the molarity of an HCl solution if 25.0 mL of NaOH (0.1 M) is required to neutralize 50.0 mL of HCl.
Solution:
- Write the neutralization reaction:
\[
\text{NaOH} + \text{HCl} \rightarrow \text{NaCl} + \text{H}_2\text{O}
\]
- Moles of NaOH:
\[
0.1\, \text{M} \times 0.025\, \text{L} = 2.5 \times 10^{-3}\, \text{mol}
\]
- Since the reaction ratio is 1:1, moles of HCl = moles of NaOH = \(2.5 \times 10^{-3}\) mol
- Molarity of HCl:
\[
\frac{2.5 \times 10^{-3}\, \text{mol}}{0.05\, \text{L}} = 0.05\, \text{M}
\]
Answer: The molarity of HCl is 0.05 M.
