Investigating temperature change when different Volumes of acid and alkali are mixed Prediction My prediction is that the biggest temperature change will be when there are equal amounts of H+ ions and OH-, this is because create an optimum mixture for the ions to neutralise each other. Apparatus * Empty plastic yoghurt cup * thermometer * Hydrochloric Acid * Sodium Hydroxide * Two measuring cylinders Diagram 30ml³ Hydrochloric acid Thermometer Measuring Cylinder Plastic cup 30ml³ Sodium Hydroxide Method First of all we decided to use a plastic cup because it was easy to wash off the mixture. We poured out 30ml of Hydrochloric acid in to one measuring cylinder and poured 30ml of Sodium Hydroxide into the other measuring cylinder. Then we added the Sodium Hydroxide to the plastic cup and left it for 25-30 seconds, we then took the temperature of the alkali before adding the acid. We then tipped the Hydrochloric acid into...
