Get to know the bench: measure 50 mL of water, transfer it and take its temperature.
Dissolve salt in water, then heat the solution until the water has gone and crystals remain.
Mix sodium chloride and silver nitrate solutions, then separate the precipitate by filtration.
Add zinc to blue copper(II) sulfate solution and watch the colour fade as copper is displaced.
Make blue copper(II) hydroxide, then heat it and watch it decompose to black copper(II) oxide.
Compare an acid, an alkali and water using universal indicator and a pH meter.
Add an alkali to an acid until phenolphthalein turns pink, and feel the heat of neutralization.
Titrate a hydrochloric acid sample against 0.100 M sodium hydroxide and calculate its concentration.
React zinc with dilute hydrochloric acid and identify the gas with a burning splint.
React marble chips with dilute hydrochloric acid and test the gas given off.
Decompose hydrogen peroxide with a manganese(IV) oxide catalyst and test for oxygen.
