A) sulphur is present in the mixture as impurity
B) IV group radicals are precipitated as sulphides
C) the oxidation of \[{{H}_{2}}S\]gas by some acid radicals
D) III group radicals are precipitated as hydroxides
Correct Answer: C
Solution :
Turbidity is due to colloidal formed, as a result of the oxidation of \[{{H}_{2}}S\]by some oxidising agent (radicals) present in the mixture. \[{{H}_{2}}S+[O]\xrightarrow[{}]{{}}{{H}_{2}}O+S\]You need to login to perform this action.
