Determination of total amount of cations in water

Different types of metal salt are dissolved in natural, industrial or any other water. Therefore, the water contains different type of cations. The cations in water can be determined by using cation exchange resin. They are electron donors and consequent positively charged. Some common cations are Na+, K+, Mg2+, Ca2+, Fe2+ or Fe3+, Mn2+, Al3+. On the other hand, cation exchange resin contains Read more

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

Water testing kits

The water testing kits are used for monitoring the quality of drinking water and controlling the important operational parameters. The kit is not given high level accurate result but it given a warp idea. This kit can help us by providing the idea about what is the condition of our water or check out how the treatment working on. Although we are not get exact result but this result is very Read more

Determination of hardness of water by EDTA method

Determination of hardness of water by EDTA method is one of the three main methods for determination of hardness of water. EDTA means Ethylenediaminetetraacetic acid. This EDTA reagent can be forming edta-metal complexes by the reaction with metal ions except for alkali metal ions. This reagent can forms a stable complex with the alkaline earth metal like calcium ion and magnesium ion in Read more
