Chemistry bench
Mix acids, alkalis, metals and salt solutions in two beakers. Watch for fizzing, colour changes and precipitates, test the gases, and read the balanced equation for every reaction.
This is a virtual lab. Never try these with real chemicals without a teacher.

What's happening
Pick a reagent from the shelf and add it to a beaker. Try dilute hydrochloric acid with universal indicator, then add sodium hydroxide a little at a time.
Challenges
0/6- Neutralise 25 cm³ of acid to pH 7 (±0.5) with sodium hydroxideAdd exactly 25 cm³ of an acid, then sodium hydroxide of the same strength. Watch the pH meter.
- Make a blue precipitateCopper(II) ions + hydroxide ions.
- Displace copper from copper(II) sulfateUse a metal more reactive than copper.
- Collect and identify the gas from chalk and acidReact chalk with an acid, then use the limewater test.
- Make hydrogen and identify itA reactive metal plus a dilute acid, then a lit splint.
- Make a white precipitate of silver chlorideSilver nitrate + something containing chloride ions.
In beaker A
Empty. Pick a reagent from the shelf.
