Lab Safety

Part of the Food Chemistry and the Lab section of Coddy's Chemistry journey. Lesson 17 of 27.

Wear safety goggles. Read the hazard symbols: corrosive, flammable, toxic.

Dilute an acid by adding the acid to the water, slowly. Never taste, eat or drink in the lab.

A beaker of 0.1 M hydrochloric acid

Even a dilute acid needs goggles

A pH near 1 or near 14 means a corrosive solution.

Challenge

Before using a bottle of $0.1\ \mathrm{M}$ hydrochloric acid, a strong acid, a student checks how hazardous it is. Work out its pH and say whether it is acidic, neutral or basic.

Try it yourself
