Chemistry practical exams can be challenging if students are not clear about titrations, salt analysis, or chromatography work. This guide on Chemistry (Practical) Model Papers Lahore Board explains the complete paper pattern in a simple, easy-to-understand format so students can prepare confidently and score well.
Chemistry Practical Paper Overview
- Subject: Chemistry (Practical)
- Level: Intermediate
- Time Allowed: 3:00 Hours
- Maximum Marks: 30
Important Note for Students
Students are required to write the principle, standard solution, end point, indicator, equation, procedure, and supposed calculations for Question 2.
For Question 3, write principle, procedure, and supposed calculations if required during the first 20 minutes of the exam.
Student Tip:
These written parts are checked carefully, so presentation and correct sequence matter a lot.
Question 1: Salt Analysis (10 Marks)
- Identify the given salt “B”
- Perform dry tests and wet tests
Student Tip:
Practice common anions and cations reactions and remember confirmatory tests.
Question 2: Volumetric Analysis (10 Marks)
- The given solution contains 27.8 grams of FeSO₄·7H₂O per dm³
- Find the amount of iron in the given sample volumetrically
Students must clearly write:
- Principle
- Standard solution
- Indicator
- End point
- Chemical equation
- Procedure
- Calculations
Student Tip:
Always show units properly in calculations to avoid mark deduction.
Question 3: Paper Chromatography (4 Marks)
- Separate the mixture of inks using paper chromatography
