Question

Fter carrying out some tests at a local stream, you discover that the pH in the stream is extremely low. Based on this, you should tell your friends to A) go home and play Xbox. B) build a raft to raft down the stream. C) swim in and drink the water from the stream. D) not swim in or drink the water from the stream.

Answer 1

Not swim in the stream or drink its water.

Option: D

Explanation:

The pH of water is 7, but according to the question, the pH of the local stream is extremely low that means the alkalinity level of the water is very low. This will cause damage to the persons in the water, the pipes in the pool and also the walls of the pool will get damaged by the low pH of water in the pool. The water was extremely low pH will be acidic that means it will be soft and corrosive. It will destroy the metals used in the pool like copper, zinc and lead, so it can easily harm humans too. So I will wisely suggest my friends not to swim or to drink the water from that.

Answer 2

D) not swim in or drink the water from the stream

Step-by-step explanation:

Low pH means the water is acidic which is harmful to your skin as it can cause burns and irritations. So any means of contacting with water is not healthy. The damage to the skin happens as in acidic water it has more H+ than in the neutral water and the extra H+ ions can ionize the atoms which are combined to form different compounds in the skin when in contact.
