Physico-Chemical Analysis of Water

Physico-Chemical Analysis of Water thumbnail
Quality water is necessary for all living things.

Physicochemical analysis of water is the analysis of the physical and chemical properties of a sample of water, often to determine if the water is suitable for drinking or supporting aquatic life.

  1. Dissolved Oxygen

    • The amount of dissolved oxygen in a sample is measured in milligrams per liter with a dissolved oxygen kit.

    Temperature

    • The temperature of the water is measured with a thermometer in either degrees Celsius or degrees Fahrenheit.

    The pH

    • The pH of water is measured with a pH meter. A pH of more than 7.0 indicates basic water, while a pH of less than 7.0 indicates acidic water.

    Color and Odor

    • The color of water is measured by comparison and the odor by the use of the examiner's sense of smell.

    Total Hardness

    • Total Hardness is measured in milligrams per liter of CaCO3 (calcium carbonate).

    Electrical Conductivity

    • Electrical Conductivity is a measure of the amount of salts in the water and is measured in milligrams per liter.
