Concept explainers
Interpretation:The correct answer referring to corrosive wastes from the given options
Concept Introduction:
Corrosive wastes are those wastes that can corrode easily or dissolve material in contact. They can be acidic or basic depending on the pH value. If the pH value of solution is less than equal to 2 or more than equal to 12.5, the solution is said to be corrosive in nature. The solution with pH less than equal to 2 is acidic in nature and the solution with pH more than equal to 12.5 is basic in nature.
Correct answer:The correct answers are option (a) Sodium hydroxide and option (d) phosphoric acid
Reason for correct option: Sodium hydroxide and phosphoric acid are corrosive in nature. Here, sodium hydroxide is base with pH 13 and phosphoric acid is acid with pH range of 1.08-2.26.
Reason for incorrect option:Option (b) Sr metal and option (c) trinitrotoluene are not corrosive wastes. Because their pH value does not lie in the pH range of corrosive substances.
