Easy preparation
Utensils: soda ash, vinegar, containers (such as discarded beverage bottles, cans), plastic sticks, small spoons.
step:
① Pour 2 and a half spoons of vinegar into the container, and add half a spoon of soda ash.
②Stir it evenly with a plastic rod to make it dissolve as much as possible.
③Dispose of the experimental area and discard the experimental waste liquid diluted 1:10 to avoid environmental pollution.
Phenomenon: A large number of bubbles overflow quickly, and the soda ash is gradually dissolved
Advantages: The method is simple, the materials are easy to find, and you can experience the joy of experimentation at home.
Disadvantages: The generated sodium acetate cannot be used for experiments, there is no treatment facility, and the experiment accuracy is poor.
Principle: (The reason is the partial ionization of weak acid) Magic Purpose: It can be used to perform ice catching magic in water
