Step-by-Step Practical
Explanations
1. pH Determination
- Procedure: Calibrate pH meter with
standard buffers. Measure sample pH directly.
- Application: Water quality analysis.
2. Alkalinity of Water
- Procedure: Titrate water with standard
acid using phenolphthalein/methyl orange.
- Application: Important for boiler feed water
treatment.
3. Acidity of Water
- Procedure: Titrate water with standard
base using indicators.
- Application: Indicates corrosiveness of
water.
4. Water Hardness
- Temporary
Hardness:
Removed by boiling.
- Permanent
Hardness:
Determined using EDTA titration.
- Application: Useful for industrial water
treatment.
5. Chloride Content
- Method: Argentometric titration with
silver nitrate.
- Application: Measures salt contamination.
6. Iron Content (Colorimetric)
- Method: Form colored complex, measure
absorbance.
- Application: Environmental analysis.
7. Copper in Brass
- Procedure: Dissolve brass, estimate copper
volumetrically.
- Application: Alloy quality testing.
8. Total Solids in Water
- Procedure: Evaporate water, weigh residue.
- Application: Check water purity.
9. Dissolved Oxygen
- Method: Winkler’s method.
- Application: Measures water pollution.
10. Viscosity
- Method: Ostwald viscometer.
- Application: Lubricants, industrial fluids.
11. Surface Tension
- Method: Drop count method.
- Application: Paints, inks, detergents.
12. Conductivity
- Method: Conductivity meter.
- Application: Ionic strength measurement.
13. Paint Composition After Heating
- Observation: Weight decreases due to
evaporation of volatile matter.
14. Use of Desiccator
- Purpose: Keep samples moisture-free
after heating.
15. Effect of Temperature on Reactions
- Observation: Reaction rate increases with
temperature (Arrhenius principle).
