“11th Class Chemistry Chapter 2 Quiz: Experimental Techniques in Chemistry” throws light on the different methods and instruments used in chemistry to carry out experiments, analyze substances, and get the results accurate. It is very essential for MDCAT students to understand these experimental techniques since they are the basis for carrying out chemical research and solving problems that arise in the field. Our MDCAT Quiz for this chapter will gauge your understanding of the various laboratory techniques and prepare you for MDCAT-related questions.
This chapter gives an overview of the importance of precision and accuracy in laboratory experiments and the necessity of proper equipment and careful measurement. Students will become familiar with common pieces of laboratory equipment, such as balances, burettes, pipettes, volumetric flasks, and test tubes, and learn what each is used for in different experiments. The technique of weighing will be discussed, where the right use of a balance is very important to accurately measure the mass of substances. Students will learn the techniques used in measuring volumes of liquids and solutions using burettes and pipettes, especially in titration and while preparing solutions. The concept of titration will be introduced, involving the neutralization of a solution of known concentration with a solution of unknown concentration, determining the concentration of an acid or base. It emphasizes the importance of separation techniques—filtration, distillation, and chromatography—for the isolation and purification of substances. Filtration separates solids from liquids; distillation separates mixtures of liquids that have different boiling points. Chromatography allows for the separation of different components present in a mixture according to their different rates of movement through a stationary phase. Other methods for separating solids from liquids are covered: evaporation and condensation. Lastly, safety protocols in the laboratory will also be discussed: the use of proper personal protective equipment (PPE), the safe handling of chemicals, and keeping a clean and orderly workspace.
