Which component is responsible for killing bacteria in water?(a) Low c

1.	Which component is responsible for killing bacteria in water?(a) Low concentration of OH-(b) High concentration of OH-(c) High concentration of acid(d) Low concentration of acidThe question was asked in exam.I need to ask this question from Inorganic Chemical topic in division Inorganic Chemical Industries of Chemical Technology
Answer» The correct choice is (b) High concentration of OH- Explanation: Because of the higher concentration of hydroxide ION maintained to kill bacteria and insure a reasonable removal of MG as Mg(OH)2, this effluent water MUST be re-carbonated to neutralize the EXCESS alkalinity.
