What role does the glass rod play in the chemical experiment?

The function of glass rod in chemical experiment;

1. Filtration and other conditions.

2. Used for stirring under the conditions of dissolution and evaporation.

3. Transfer of liquids and solids.

4. Initiate a reaction, such as igniting red phosphorus.

5. Evenly disperse the heat.

Glass rods are used in chemical experiments. Glass slender rod-shaped simple agitator, also known as glass rod, is the most commonly used in middle school experiments and an essential experimental article.

Extended data

1, basic parameters

(1) main component: silica.

(2) Physical properties: high hardness, high melting point, insoluble in water, colorless and transparent.

(3) Chemical properties: inert, non-reactive with water and acid (except HF).

2. Preventive measures

(1) Don't stir too hard, so as not to break the glass rod or container (such as beaker).

(2) Don't collide with the container wall and bottom when stirring, and don't make any noise.

(3) Stir in one direction (clockwise or counterclockwise).
