First Year Chemistry Chapter 2 Online Short Questions Preparation for 1st Year Chemistry Chapter 2 Experimental Techniques in Chemistry Preparation

Annual exams are challenging and competitive now a days. The marking distributions are tightly marginalized in science subjects specifically.Short question hold 40% marks out of total marks in fsc. That’s why ilmkidunya is providing you the ease and you can prepare for the 11th class Chemistry Course content in the form of Short Questions and in a very easy way here ilmkidunya provides the Chapter 2 (Experimental Techniques).it also Provides Online Test System.

In this chapter students can cover the following topics in a very easy way.

  • A complete characterization of a compound that comprise qualitative and quantitative analyses.

  • A quantitative analysis of a compound basically involves four major steps.

  • The process of filtration is used to separate insoluble particles from liquids and it can be performed with more than one types of filter media.

  • If the process of filtration is used with the filter paper it run smoothly, the stem of the funnel should remain full of liquid until there is liquid in the conical portion.

  • The filtering operation with the filter paper could be very time consuming if it were not aided by a lenient suction as liquid go through the stem.

  • The rate of filtration can be greatly increased using fluted filter paper.

  • A solid compound is cleared by crystallization from a suitable solvent. A solvent for crystallization should be able to dissolve the solute at high temperature and the maximum amount of the solute should be thrown out by the solvent when the solution is cooled.

  • The process of sublimation includes converting a solid directly into vaporous and these vapors are then concentrated to form solid again.

    • In order to achieve great score in exams student must try to learn and work hard every day they can easily learn short questions of every chapter by studying online from ilmkidunya.com website.
