| Question | Answer |
| Two Solutions that will form a precipitate. | Copper Sulphate Sodium Carbonate |
| Complete the gaps: Zn(s) + H2SO4 | __ __(aq) + H2 (_) | ZnSO4 (aq) + H2 (g) |
| Describe the test for Hydrogen Gas. | Hydrogen Extinguishes a lit split and a squeaky pop is heard. |
| Describe what happens to Copper Atoms and Ions in acid during a reaction. | Positive Copper Ions and negative Chloride atoms form Copper Chloride. Hydrogen Ions react with the oxide to form water Copper Oxide + Hydrochloric Acid | Copper Chloride + Water |
| Products formed between Hydrochloric Acid (HCl) and Sodium Carbonate (NaCO3) | 2HCl + NaCO3 | 2NaCl + CO2 + H2O |
| How is a Titration used? | Slowly add the acid from the burette to the alkali in the conical flask, swirling the mix until the indicator changes colour. |
| Products formed by reacting CoO and HNO3. | CoO + 2 HNO3 | Co(NO3)2 + H2O |
| Products formed between Al(OH)3 and HCl | HCl + Al(OH)3 | Al(Cl)3 + H2O |
| Describe Titration | Slow addition of one solution to another until it reaches neutralisation (colour change) |
| How would you tell which solution contained the higher concentration? | The greatest volume of acid needed would show the highest concentration of aluminium. |
| Products formed in Neutralisation. | H20 H^+ + Oxygen Carbonate form CO2 from CO3, makes H2O |
| What happens when Sulphuric Acid reacts with iron to form iron (II) sulphate and hydrogen gas? | Fe(s) + H2SO4 (aq) -> FeSO4 (aq) + H2 (g) |
| What is the metal compound and solution? | Compound = Copper Carbonate Solution = Copper Chloride |
