.

Just so, why is it important to use a glass stir rod instead of a metal one?

Stirring rods are important because stirring a solution, which is also known as agitation, causes a reaction to happen faster. Glass rods are also used to spread liquid substances on a solid surface. It is preferable to a metal rod because glass is not a good conductor of heat and metal is. Metal has free electrons.

Beside above, why is it necessary to wash the solution off the stirring rod into the beaker? To speed up dissolving of the sodium carbonate, and to prevent the formation of hard lumps of the substance. (iii) Why is it necessary to wash the solution off the stirring rod into the beaker? To ensure that all of the sodium carbonate solution is transferred to the volumetric flask.
