The experimental procedure for blowing clear lime water
Principle: Lime water is calcium carbonate aqueous solution of carbon dioxide + = calcium carbonate (white precipitate) + water
The device produces a carbon dioxide generator, a homogeneous generator phenomenon, clarifies the lime water to become turbid, and then passes through the carbon dioxide to eliminate turbidity and clarify the edge
1. add 1/3 volume of clarified lime water to the test tube2. insert a glass tube in the test tube and use the mouth to clear the carbon dioxide in the clear lime water,Soon, clarified lime water became cloudy, and white insoluble substances, calcium carbonate, were generated
