This 9th class chemistry chapter 13 test is an original ExamPaperDesk practice paper for Chapter 13, Laboratory and Practical Skills. Every question appears in both English and Urdu, so English medium and Urdu medium students can sit the same paper. It carries 36 marks and follows the board pattern exactly: 10 multiple-choice questions with a bubble sheet, 10 short questions of which you attempt any eight, and 2 detailed questions. An answer key for the MCQs is printed on the last page so you can mark Section A yourself.
What the Chapter 13 Test Covers
The questions are spread across the whole chapter rather than one section of it, so the paper is a fair check of whether you are ready. Topics you will meet include:
- hazard labels such as Corrosive
- self-reactive and explosive chemicals
- flashpoint and flammable liquids
- chemicals that react violently with water
- chemical asphyxiants
- radiation that injures the body from outside
Paper Pattern
- Section A — 10 MCQs, 1 mark each, with a bubble sheet to fill like the real answer sheet.
- Section B — 10 short questions, attempt any eight, 2 marks each.
- Section C — 2 detailed questions, 5 marks each.
- Total — 36 marks, with an MCQ answer key at the end.
How to Use This Chapter 13 Test
Print the paper or open it on your phone, put your book away, and attempt all three sections in one sitting as you would in an exam. Fill the bubble sheet for Section A, then mark it against the key on the last page. For Sections B and C, compare your answers with the Chapter 13 solved exercise notes and note any question where your answer was correct but incomplete — in the board exam those are the marks most students lose.

Also Examined in This Chapter
- Laboratory safety rules and the standard hazard symbols.
- Correct use of the balance, burette, pipette and measuring cylinder.
- Filtration, evaporation, crystallisation, distillation and sublimation as separation techniques.
- Chromatography and the calculation of Rf value.
- Titration technique, including rinsing and reading the burette.
Statements That Must Be Exact
- Always add acid to water, never water to acid, because dilution releases a great deal of heat.
- Read the bottom of the meniscus at eye level to avoid parallax error.
- Rf value equals the distance moved by the solute divided by the distance moved by the solvent front, and is always less than one.
Where Marks Go Missing
- Adding water to concentrated acid.
- Reading the meniscus from above or below eye level.
- Writing down the observation you expected instead of the one you actually saw.
Frequently Asked Questions
Why must acid be added to water rather than water to acid?
Because dilution is strongly exothermic. Adding acid slowly to a large volume of water spreads that heat safely, whereas adding water to concentrated acid can make it boil and spit.
