No. Chemicals should be disposed of in a safe manner. Usually directions for disposal can be found on the box/tube/packet that the chemical came in. If none can be found, ask a professional (teacher, lab assistant, poison control expert) what is the proper disposal for a certain chemical. Excess materials poured down the drain may be poisonous to the environment or people, and can leak from the sewage system to our ground water and eventually to our food.

Can any excess materials that are not used during a laboratory experiment may be poured down the drain?
Most of the substances used in most laboratory experiments can be safely poured down a drain. However, laboratory experiments sometimes involve corrosive substances which would damage the plumbing if poured down the drain; they can also involve chemicals which, if they were to be mixed together as they are poured into the same drain, would undergo chemical reactions that might cause an explosion or a fire. And it is also possible that you are conducting experiments on highly toxic materials that would become an environmental hazard if poured down the drain. So not everything goes down the drain. You have to understand the nature of the substances that you are dealing with. Some thing go to a hazardous waste center instead, or can be neutralized in your own laboratory before you dispose of them.
