Aim:
To test the dissolution of given salt is exothermic or endothermic.
Principle:
If the reaction or process liberates the heat, then it is called exothermic.
If the reaction or process absorbs the heat, then it is called endothermic.
Apparatus required:
Two beakers, Thermometer, stirrer, weighed amount of two samples.
Procedure:
Take 50ml of water in two beakers and label them as A and B. Note the temperature of the water from beaker A and B. Then, add 5g of sample A into the beaker A and stir well until it dissolve completely. Record final temperature of the solution. Now, repeat the same for the sample B. Record the observation.
Observation:
Result:
From the inferences made
The dissolution of sample A is ____________________(Exothermic or endothermic)
The dissolution of sample B is ____________________(Exothermic or endothermic)
Note:
Sodium hydroxide, ammonium nitrate, glucose, calcium oxide etc. may be given as the sample.
