level questions: Neutralisation and Titrations
| Question | Answer |
|---|---|
| What is titration | A technique that measures the volumes of acid and alkali solutions that are needed for a neutralisation reaction |
| How is the strength of a an acid determined | How much it ionises in water |
| Weak acids | Only partially ionise in water meaning that not all the acid molecules break up to form H+ ions Ethanoic acid and most acids are weak |
| Strong acids | Fully ionize in water meaning that all the acid molecules break up to form H+ ions Hydrochloric acid, sulfuric and nitric acid |
| Key variables when neutralising an alkali with an acid | titration could be used to calculate the concentration of alkali if we knew the concentration of acid to be added and the volumw of the alkali |
| What indicators could be used if both the acid and alkali are strong | methyl orange which turns yellow in alkali and red in acid phenolphtalein which turns pink in alkali and colourless in acid |
