What the sim shows
Each tube holds 10 cm³ of 2.0 mol/dm³ hydrochloric acid. A metal above hydrogen in the reactivity series gives a salt and hydrogen: the metal is oxidised and the hydrogen ions are reduced, so the chloride ions are only spectators. The higher the metal, the faster it fizzes. Iron(II) chloride makes the solution pale green. Copper is below hydrogen, so it gives no gas at all. The chart is a race to 10 cm³ of hydrogen: the sooner a metal gets there, the faster it reacts (a bigger piece only gives more gas in the end, which says nothing about speed). The masses are 0.024 g of magnesium ribbon and 0.10 g each of the others; how fast each one reacts is this figure's estimate of a school result. The clock runs 20 times faster than real time.

- Iron and sulfur: mixture or compound? simPull iron out of an iron and sulfur mixture with a magnet, then heat a fresh mixture until it glows and forms black iron(II) sulfide, which the magnet no longer attracts, and find the fixed proportion from your own masses.
- Making a salt by titration simTitrate with methyl orange, repeat with the same volumes and no indicator, then crystallise sodium chloride, sodium sulfate or the fertiliser ammonium sulfate and work out the yield.
- Making a standard solution and diluting it simWeigh a solid, dissolve it, transfer it with rinsings to a volumetric flask, make up to the mark and invert; then dilute with a pipette. Concentrations in mol/dm³ and g/dm³, and what each slip in technique does to them.
- Which metal oxides can carbon reduce? simHeat the oxides of magnesium, zinc, iron, lead and copper with carbon, in hydrogen, and in competition with other metals. Real data decide each result, and a results table builds the reactivity series and shows why each metal is extracted the way it is.
- Moles of gas from magnesium and acid simWeigh magnesium ribbon, drop it into hydrochloric acid and collect the hydrogen in a gas syringe. Plot the volume against moles of magnesium to measure 24 dm³ per mole, and watch the line level off when the acid runs out.
- Neutralising acid with lime simAdd weighed spatulas of calcium hydroxide or calcium oxide to dilute hydrochloric acid, stir, read the pH meter and plot pH against mass added; then lime a pot of acid soil.
