You are given solutions of sodium hydroxide and ammonia of the same concentration. Describe and give the results of a test to show that sodium hydroxide is a stronger alkali than ammonia solution | Add universal indicator; ammonia would go blue (pH of 9or10) whilst sodium hydroxide go purple (pH=12to14) OR (TRIPLE ONLY) do a titration with HCl; you would need more HCl for Sodium Hydroxide |
TRIPLE ONLY: Sodium hydroxide is a strong alkali. In terms of ionisation, what is meant by the word strong? | A STRONG alkali (or acid) is TOTALLY dissociated |
Name or give the formula of the ion that makes solutions alkaline. | Hydroxide ions (OH)-1 |
Name or give the formula of the ion that makes solutions acidic | Hydrogen ions (H)+1 |
Describe how you would collect pure dry crystals of Copper Sulphate from Sulfuric acid and Copper Oxide | YOU MUST LEARN THIS! Warm the Sulfuric acid; Add Copper Oxide to Sulfuric Acid; until Copper Oxide does not dissolve anymore; filter the excess of Copper Oxide; heat gently until the first crystals form; leave to to crystallise further at room temperature |
(HIGHER) What is the ionic equation for the reaction between an acid and an alkali | H+ + OH- ---> H2O |
Which ion causes a solution to be pH 3? | the solution is acidic; the ion that causes solutions to be acidic is H+ |
When collecting pure dry crystals of Copper Sulphate from Sulfuric acid and Copper Oxide, why do you need to warm up the Sulfuric acid? | to speed up the reaction |
When collecting pure dry crystals of Copper Sulphate from Sulfuric acid and Copper Oxide, why is Copper Oxide until no more dissolve? | to ensure that copper oxide is IN EXCESS; to ensure that all the Sulfuric acid has reacted |
When collecting pure dry crystals of Copper Sulphate from Sulfuric acid and Copper Oxide, why do you need to filter the Copper Oxide | to remove the EXCESS of copper oxide |
How would the pH change when Copper Oxide is added to Sulfuric acid? | the pH would go from 1 to 7 because the acid would be slowly neutralised; it would not go up further because Copper oxide does not dissolve in water |
(HIGHER) What is a weak acid? Give an example | an acid that is partially dissociate: Ethanoic Acid dissociates only partly into Ethanoate ions and Hydrogen ions |
(HIGHER) What is a strong acid? Give an example | an acid that is completely dissociated: Sulfuric Acid dissociates only partly into Sulfate ions and Hydrogen ions |
(HIGHER) What happens to the pH when you dilute a solution of a strong acid 10 times? | The pH will increase by 1 unit |
Which salts are always soluble? | SNAP: sodium, nitrate, ammonium, potassium |
Which salts are always insoluble, and used as chemical tests in precipitation reactions | Barium Sulfate and Silver Chloride |
