(1) Inorganic anions such as chloride , nitrate and sulphate can be separated in about five minutes.

(2) Sodium chloride

(3) A chemical reaction takes place between sodium, potassium and magnesium chlorides from salt with calcium oxides and hydroxide from soil to form calcium chloride.

(4) Leachate typically contains organic compounds together with metal chlorides and sulphates, and has a high chemical oxygen demand due to the presence of reducing species.

(5) The carboxyl group is fairly reactive, and carboxyl group-containing compounds can undergo nucleophilic substitution to form many useful derivatives such as acid chlorides , anhydrides, esters, and amides.

(6) Heating with alkyl chlorides gives a mixture of the mono and the dialkyl aniline.
