    HI 38080
    Calcium and Magnesium Test Kit for Soil

    Product Description:

    Hardness in water is mainly due to the presence of Calcium and Magnesium ions and each contributes to the amount of total hardness. Monitoring and controlling hardness is instrumental in order to prevent scaling and corrosion.

    The HI 38080 test kit extracts calcium and magnesium from soil in acidic medium and then determines them via a titrimetric method. The indicator chelates with the calcium and magnesium ions to form a red colored complex. As EDTA is added, calcium and magnesium complex with it, and the reaction endpoint is indicated by a change in color of the indicator from red to blue.
