Does baking soda raise or lower the water temperature?

Answer by  vinomanju (15)

Baking soda and water is exothermic and so the water gets a little warmer. Because the chemical bonds of the products has excess binding energy than components.

Baking soda and water is an endothermic reaction, so it lowers the water temperature. You can try this at home with a cup of hot water and some baking soda. Measure the temperature when the water is still hot, and then pour down the baking soda. The temperature should then begin to steadily lower.

Baking soda (Sodium bicarbonate) causes an exothermic reaction in the water which causes the water's temperature to lower. At the same time the baking soda dissolves in the water within a minute of putting the baking soda in the water.

Answer by  jsmith (2067)

Dissolving baking soda in water is an exothermic reaction so it will ever so slightly raise the temperature of the liquid. As the sodium bicarbonate dissolves, one of the products is carbon dioxide gas. This gas bubbles up and leaves the liquid. Each departing gas molecule carries some thermal energy away from the water and lowers the net temperature.
