Titration in NECO Chemistry Practical
Titration is usually Question 1 and carries many marks.
This part requires accuracy and careful reading.
What is Titration?
Titration is a laboratory method used to determine the concentration of an unknown solution using a solution of known concentration.
Important Titration Terms
| Term | Meaning |
|---|---|
| Titre Value | Volume used during titration |
| End Point | Point where colour changes |
| Indicator | Substance showing colour change |
| Meniscus | Curve seen in liquid measurement |
| Concordant Values | Close titre values |
Steps for Accurate Titration
- Rinse apparatus properly
- Fill burette carefully
- Remove air bubbles
- Read initial burette value
- Add indicator to flask
- Titrate slowly near endpoint
- Record final reading
- Calculate titre value
Common Indicators and Colours
| Indicator | Acid Colour | Alkali Colour |
|---|---|---|
| Methyl Orange | Red | Yellow |
| Phenolphthalein | Colourless | Pink |
The Complete Guide to NECO Chemistry Practical 2026 strongly recommends practicing at least five titration experiments before the examination.
Example of Titration Calculation
Example Question
25.0 cm³ of sodium carbonate solution reacted completely with 20.0 cm³ of hydrochloric acid of concentration 0.1 mol/dm³. Calculate the concentration of sodium carbonate.
Solution
Balanced equation:
Na₂CO₃ + 2HCl → 2NaCl + H₂O + CO₂
Step 1: Calculate moles of HCl
Moles = Concentration × Volume/1000
= 0.1 × 20/1000
= 0.002 mol
Step 2: Use mole ratio
1 mole Na₂CO₃ reacts with 2 moles HCl
Therefore:
Moles of Na₂CO₃ = 0.002 ÷ 2
= 0.001 mol
Step 3: Calculate concentration
Concentration = Moles ÷ Volume
= 0.001 ÷ 25/1000
= 0.04 mol/dm³
Answer = 0.04 mol/dm³
Qualitative Analysis in NECO Chemistry Practical
