1 of 16
What do we call very unreactive metals such as gold and platinum?
Native metals
2 of 16
Whats the Displacement Order?
A metal can only displace another metal from a compound if it is located above it in the reactivity series.

What is a Displacement Reaction?
A more reactive metal (one that forms positive ions more easily) can displace a less reactive metal from a compound.

How do you make soluble salts?
Soluble salts can be made by reacting acids with solid, insoluble substances such as pure metals, metal oxides, metal hydroxides, or metal carbonates.

How do you prepare for the required practical: Separating mixtures
1.Gently warm an acid using a Bunsen burner 2. Add the insoluble solid (with stirring) until no more reacts.

How do you filter everything in the required practical; Separating mixtures
Filter the solution to remove the excess insoluble solid. This will leave a solution of the salt dissolved in water.

How do you do the crystallisation step in the required practical: Separating Mixtures?
1. Heat the solution in an evaporating basin above a beaker of water. The 'water bath' ensures gentle heating. 2. Leave the solution to cool and allow more water to evaporate. The solution will become more concentrated and the salt will crystallise
