5 Best Chemistry Practicals for Class 9: Experiment, Theory, FAQs

Practicals are a very engaging part of the study for the students. If you ask the students, they prefer practicals over theoretical subjects as they find practicals more exciting and easy to understand. 

Chemistry is a subject with a lot of chemicals and reactions. You cannot understand every reaction by just phrasing them. You need to have a deep understanding of the chemicals and their properties.

Usually, students pay attention to theory rather than practical, as theory contains more marks. In reality, nobody puts pressure on practicals as teachers give marks easily in the practicals so that students can focus on their main theory examination.

Today we’ll give you a brief about the practicals given in class 9. You can also check out the NCERT Solutions for Class 9 Science, where all the experiments are explained in a well-mannered form.

List of practicals for class 9 chemistry

Experiment 1 

Aim- Determine the melting point of ice

Theory- It is a temperature at which solid changes into a liquid that state is known as the melting point.  Once the temperature reaches its melting point, it sticks to the point until the solid fully converts into the liquid state.

Note: You can also use chemistry formulas to understand the chemical reactions and properties better

Experiment 2

Aim- Prepare the 

(i) suspension of soil, chalk powder, and fine sand in water

(ii) a true solution of common salt, sugar, and alum

(iii) a colloidal solution of starch in water and egg albumin in water and differentiate between them based on

  1. Stability
  2. Transparency 
  3. Filtration criteria

Theory-

(i) The particle size in suspension is greater, which may be observed with normal eyes or under the microscope.

(ii) Homogenous mixture of two or more substances that can’t be separated from each other. The component presented in the larger amount is known as a solvent.

(iii) Colloidal solution appears to be homogeneous. The particles can scatter a ray of light; when left undisturbed, the solutions are stable, and the particles are invisible to normal eyes. 

Experiment 3

Aim- A separation of the mixture of sand, common salt, and ammonium chloride

Theory- It is a form of heterogeneous mixture which can be separated by various physical separation methods. By selecting the suitable separation method, these can be separated.

  1. You can separate the sand in the water as it is insoluble
  2. Common salt can be recovered by evaporation
  3. Ammonium chloride sublimes on heating

Experiment 4

Aim- Determine the boiling point of the water

Theory- It is the temperature at which boiling occurs for the specific liquid.

Determine the boiling point of the water

Experiment 5

Aim- Verification of the law of conservation of mass in any chemical reaction

Theory- It states that the mass remains conserved during a chemical reaction. In this experiment, you need to verify the law of conservation of mass in any specific chemical reaction. 

Conclusion

Sometimes it’s not about marks, and you need to focus on the understanding level as well. A basic understanding of the topic is necessary to gain knowledge of the topic, which will help you in the future. These experiments will provide you with a broader understanding of the topics, which will help you in the examination. 

You can also take help from Chemistry questions and answers, which makes you achieve your goal with flying colors. Make sure to understand the experiment and then solve it. Otherwise, it can blow up the experiment as well. All the best with your preparation.

Frequently Asked Questions(FAQs)

Q1. Is matter around us a pure experiment?

Ans. It is a chapter of Class 9 Chemistry in which various experiments will brief you about the chapter and the matters as well.

Q2. Is rubber a pure substance or a mixture?

Ans. Rubber is a pure substance if we’re talking about raw rubber. 

Q3. What is distillation class 9th?

Ans. Distillation is a separation method that separates the mixture of components into individual components.
