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.
What else can I help you with?
Any excess materials that are not used during laboratory experiment may be poured down the drain.true or false?
No. False. 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.
Why would you use sodium hydrocarbon and potassium hydroxide in a photosynthesis experiment?
In a photosynthesis experiment, sodium bicarbonate is used to provide a carbon source for the plant during photosynthesis. Potassium hydroxide is used to remove any excess carbon dioxide present in the experimental setup to simulate ideal photosynthetic conditions.
What was done in the experiment to ensure that all KHCO3 was react?
In the experiment, excess HCl was added to the solution containing KHCO3. This ensured that all of the KHCO3 would react completely, as any unreacted KHCO3 would still be neutralized by the excess HCl.
What is spare material called?
Excess or additional materials are commonly referred to as scraps, leftovers, or surplus.
How will excess magnesium be removed from sulphuric acid during experiment'?
Excess magnesium in sulfuric acid can be removed by adding a dilute acid, such as hydrochloric acid, to convert the magnesium to soluble magnesium chloride, which can be filtered out. Alternatively, the solution can be allowed to stand so that any unreacted magnesium settles to the bottom, and the supernatant can be decanted.

What substances are removed from blood during dialysis?
waste materials that have toremoved by kidneys.

How would you dispose of excess amalgam?
Mercury residues are collected for recycling by an authorized laboratory.
What materials removed from the kidney?
Materials removed from the kidneys are urea and water sugar!
What waste materials comprise sweat or perspiration?
the waste materials are deadcells,excess salts and water
What wastes materials comprise the sweat or perspiration?
the waste materials are deadcells,excess salts and water
How thales experiment produce static elictricity?
Thales' experiment involved rubbing amber with fur, creating friction and transferring electrons between the two materials. This transfer of electrons led to an accumulation of excess negative charge on the amber, resulting in static electricity.
What is the use of Koplin jar in the laboratory?
to hold slides for staining or in between stains to rinse excess away with water
What materials are removed from the bloods through dialysis?
urea and excess salts

What was done in the experiment to ensurethat all KHCO3 was react?
In the experiment, excess HCl was added to ensure that all KHCO3 was reacted. Excess reactants ensure that all of the limiting reactant is completely consumed in the reaction, leaving none unreacted. When all KHCO3 reacts, the reaction reaches completion.
