Question

Fredrick is doing a lab on pH. He uses many household items to determine the pH of his items. Which of his actions best describes inappropriate lab safety?

He changes into closed-toed shoes before lab starts.
He doesn’t wear goggles because he is using household chemicals.
He asks his teacher if he can mix high- and low-pH solutions before discarding them.
He leaves his workstation to identify all of the safety equipment in the lab.

Answer 1

The correct answer is (B) because he should always wear safety garments for preventative purposes.

Answer 2

The correct answer is option B

There must be some safety and preventive measures while someone is working in the laboratory.

Chemicals are very harmful if not used with care. Low pH can burn your hands and or other parts of the body so proper precautions should be taken before starting the experiment.

If a person is not wearing goggles while performing the experiments with low or high pH chemicals then it is not good.

So, proper precautions must be taken while working in laboratory.
