Identification of the dissolution of the given salt whether it is exothermic or endothermic

To test the dissolution of given salt is exothermic or endothermic

IDENTIFY THE DISSOLUTION OF THE GIVEN SALT WHETHER IT IS EXOTHERMIC OR ENDOTHERMIC.

 

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.
