List of Chemistry Practical Experiments for B.Sc Students
Here are some of the chemistry practical experiments that you can perform as a B.Sc student:
- Spectrophotometry: This is a technique that measures the amount of light absorbed or transmitted by a substance at different wavelengths. Spectrophotometry can be used to determine the concentration, purity, or identity of a substance, as well as to study its chemical reactions and properties. You can use a spectrophotometer to measure the absorbance of different solutions and plot their calibration curves. You can also use spectrophotometry to determine the antioxidant activity of various substances, such as ascorbic acid, by measuring their ability to scavenge free radicals.
- Gravimetric Analysis: This is a method that involves the separation and weighing of a substance or its constituent element from a sample. Gravimetric analysis can be used to determine the percentage composition, molecular formula, or empirical formula of a substance. You can perform gravimetric analysis by precipitating, filtering, drying, and weighing a substance or its derivative. For example, you can determine the percentage of nickel in a sample by precipitating it as nickel(II) dimethylglyoxime and weighing it. You can also determine the percentage of calcium in milk by precipitating it as calcium oxalate monohydrate and weighing it.
- Potentiometric Titration: This is a technique that involves measuring the potential difference between two electrodes in a solution during titration. Potentiometric titration can be used to determine the equivalence point, endpoint, or pH of a solution, as well as to analyze redox reactions, complexation reactions, or precipitation reactions. You can perform potentiometric titration by using a voltmeter or a pH meter to record the potential or pH changes as you add a titrant to an analyte. For example, you can determine the concentration of an acid or a base by potentiometric titration using a standard solution of sodium hydroxide or hydrochloric acid.
- Water Quality Analysis: This is a process that involves testing the physical, chemical, and biological characteristics of water samples. Water quality analysis can be used to assess the suitability of water for various purposes, such as drinking, irrigation, industrial use, or aquatic life. You can perform water quality analysis by measuring various parameters, such as alkalinity, hardness, chloride, dissolved oxygen, total dissolved solids, total suspended solids, total solids, and pH. You can also compare the results with the standard values prescribed by various agencies.
- Chromatography: This is a technique that involves separating the components of a mixture based on their different affinities for a stationary phase and a mobile phase. Chromatography can be used to identify, isolate, purify, or quantify the components of a mixture, as well as to study their interactions and properties. You can perform chromatography by using different types of stationary phases (such as paper, thin layer, column, or gas) and mobile phases (such as solvents or gases). For example, you can identify amino acids in a mixture by thin-layer chromatography using silica gel as the stationary phase and butanol-acetic acid-water as the mobile phase.
