Question 7 • Physical Science

Why is a protective apron or lab coat important to use when working with acids?

Answer
A
Acids react with lipids and can cause damage to skin tissue.
B
Acids break down fabrics and can cause burns if the acids are strong.
C
Acids have a slippery feel and could result in a fall.
D
Acids conduct electricity and contact could cause a shock.

Explanation

Strong acids are corrosive: they can damage or break down clothing and cause chemical burns if they contact skin. A protective apron or lab coat helps protect both your clothes and your body. The reaction with lipids described in choice B is more characteristic of strong bases.
