EHS209 · UNIT 1: Measurement of pH of solutions

The pH scale is used to rank solutions as acidic or basic (alkaline). The pH scale ranges from 0 to 14. A pH below 7.0 is acidic, above 7.0 is alkaline, or basic while pH of 7 is considered neutral.

What you should be able to do

  1. Measure the pH of solutions using various methods.
  2. Perform qualitative tests to identify carbohydrates, amino acids, and lipids.
  3. Conduct quantitative estimations of carbohydrates, proteins, lipids, and vitamins.
  4. Apply paper and thin layer chromatography techniques for separation and analysis.
  5. Interpret experimental results and draw conclusions based on biochemical principles.
