1. Titration
Titration is a widely used analytical technique to determine the concentration of a substance in a solution. The experiments related to titration may include:
- Acid-base titration to determine the concentration of an unknown acid or base
- Redox titration to determine the concentration of a substance undergoing a redox reaction
2. Salt Analysis
Salt analysis involves the identification and characterization of various cations and anions present in a given salt mixture. Students are expected to perform qualitative analysis using specific reagents and conduct confirmatory tests to identify the ions present.
3. Preparation of Inorganic Compounds
In this experiment, students learn the preparation of inorganic compounds such as:
- Copper(II) sulfate crystals
- Potassium ferrocyanide crystals
- Potassium permanganate crystals
- Silver nanoparticles
4. Organic Chemistry
The experiments in this section are focused on organic chemistry concepts. Students perform various experiments involving:
- Preparation of organic compounds like formalin, acetanilide, and aspirin
- Identification of functional groups present in organic compounds using chemical tests
5. Surface Chemistry
Students explore surface chemistry concepts through experiments like:
- Preparation of lyophilic and lyophobic sols
- Determination of the surface tension of liquids using capillary rise method
6. Rate of Reaction
Experiments related to the rate of reaction help students understand the factors influencing the rate of a chemical reaction. These experiments may include:
- Effect of concentration on the rate of reaction
- Effect of temperature on the rate of reaction
- Effect of catalyst on the rate of reaction
