This chapter is about electrical conductivity (EC), which helps in checking the purity of distilled and deionized water. EC is a measure of the ability of water to conduct an electric current and depends on the concentration of the ions (higher concentration, higher EC), the temperature of the solution (high temperature, higher EC), specific nature of the ions (higher specific ability and higher valence, higher EC).
pH is the way of expressing the hydrogen ion concentration in water. It is related to the acidic or alkaline nature of water. Consideration of…
Air pollution is the presence of a substance in the air in sufficient concentration and perceptions time so as to be, or threaten to be,…
