A student reacts 25.0 cm³ of 1.00 mol/dm³ hydrochloric acid with different volumes of sodium hydroxide solution in a Styrofoam cup and records the highest temperature reached each time.
Which change would give a larger temperature rise for the same neutralisation reaction?
Which change would give a larger temperature rise for the same neutralisation reaction?
- Using a glass beaker instead of a Styrofoam cup
- Stirring the mixture less frequently
- Using a lid on the Styrofoam cup
- Using a larger volume of acid at the same concentration
