What happens when you mix water with soda ash?

Our hypothesis is, Once we mix the Water and the Soda Ash it will foam up. The reaction would be Endothermic because Exothermic occurs when the temperature  of the system increases due to the evolution of heat.

Water and Soda Ash Experiment

1- Measure 100 mL of water and pour into a beaker. Place LabQuest temperature probe into beaker.

2- Measure 1 tablespoon of soda ash and pour into beaker with water.


At the end of the 5 minutes the soda ash dissolved in the water.

Unbalance formula: NaOH + H2CO3 = 2 H2O +Na2CO3

Balance formula: 2NaOH + H2CO3 = 2 H2O +Na2CO3
