Several factories were pouring their wastes in rivers A and B. Water samples were collected from these two rivers. It was observed that sample collected from river A was acidic while that of river B was basic. The factories located near A and B are
(a) Soaps and detergents factories near A and alcohol distillery near B.
(b) Soaps and detergents factories near B and alcohol distillery near A.
(c) Lead storage battery manufacturing factories near A and soaps and
detergents factories near B.
(d) Lead storage battery manufacturing factories near B and soaps and
detergents factories near A.
According to the research, it was recorded that:
the samples from River A was acidic whereas
the samples from River B was basic.
We have seen in cars, the lead acid batteries and also we know that lead is the major constituent in these batteries.
As a result the discharge from these batteries is always acidic and acidic substances always have low pH values.
As because the samples from River A was acidic, the factory near it would be Lead storage battery manufacturing factories, which is in option (C).
Therefore, according to the same option, the factory near River B which was making the water basic was soaps and detergent factory.
So, option (C) is correct.
