| Question | Answer |
| Acids turn blue litmus | Red |
| Acids ___ bases | neutralise |
| 3 lab examples of acids | HCl (Hydrochloric acid) H2SO4 (Sulfuric acid ) HNO3 (Nitirc acid) |
| Acids can be ____, _____ or ____ | monobasic, dibasic, or tribasic |
| 3 everyday examples of acids | CH3COOH (vinegar) Lemon juice (Citric acid) Car batteries ( dilute sulfuric acid) |
| Everyday application of the neutralisation of a base by an acid | Indigestion ( excess acid in the stomach) magnesium hydroxide / sodium hydrogencarbonate neutralises the HCl |
| Bee stings are ____ and can be treated with _______ | acidic - sodium hydrogen carbonate |
| Lime's use | A base (calcium hydroxide) is used in agriculture to neutralise acidic soil. |
| Bases turn red litmus | Blue |
| Bases _____ acids | neutralise |
| 3 examples of lab bases | NaOH (sodium hydroxide) Na2CO3 (sodium carbonate) NH3 (ammonia) |
| 3 examples of household bases | NH3 (Ammonia for cleaning) NaOH (Sodium hydroxide for oven cleaners) laxitive (Magnesium hydroxide) |
| A base that dissolves in water and an example | Alkali Sodium hydroxide (solution is said to be alkaline) |
| When an acid reacts with a base | A salt is formed |
| An Arrhenius acid | A substance that dissociates in aqueous solution forming hydrogen ions. |
| An Arrhenius base | Is a substance that dissociates in aqueous solution forming hydroxide ions. |
| A Bronsted-Lowry base | A proton acceptor |
| A Bronsted-Lowry acid is | A proton donor |
| The stronger / weaker the acid | The more / less readily it donates a proton |
| The stronger / weaker the base | The more / less readily its accepts a proton |
| Advantages of the Bronsted-Lowry theory | Deals with reactions outside water Explains how substances can be amphoteric Shows how the hydronium ion is formed when an acid reacts with water |
| An amphoteric substance | Can act as an acid with a base and as a base with an acid. |
| Conjugate acids and bases | Differ by the presence or absence of a proton |
| A conjugate acid is formed when | A proton is donated to a Bronsted-Lowry base |
| A conjugate base is formed when | a proton is removed from a Bronsted-Lowry acid |
| A conjugate acid-base pair | is an acid and a base that differ by the presence or absence of a proton. |
| The stronger the acid the ____ its ______ | weaker its conjugate base |
| The stronger the base the ___ its_____ | weaker its conjugate acid |
