Determination of chloride in water by mohr method

Mohr method is one of the significant methods for determination of chloride in water. It is also known as Argentometric method. Chloride ion is a negatively charged ion. This method is appropriate for neutral or slightly alkaline water. Water sample is titrating against standard AgNO3 solution by using potassium chromate indicator. It is a precipitation titration method. Table of Read more

Swimming pool pH balance – maintaining pool water pH level

The swimming pool pH level is one of the most significant factors in pool water balance. The pH is the determination of the acidity or alkalinity of the water. pH means hydrogen ions molar concentration in a solution. It is calculated by the formula –log[H+]. The pH level is measured from 0 to 14, whereas pH 7.0 is neutral. When the pH is below 7.0 then it is called acidic. Conversely, Read more
