Pipetting by mouth risks ingesting the chemical you are trying to suck into the pipet. Even if the solution is harmless, you can't be sure that the pipet itself is clean. Who knows what chemical was in it last? Instead, use a pipet bulb or syringe to draw up the solution. These are generally available in any laboratory where you might need to use a pipet.

Don't Play Mad Scientist (Don't haphazardly mix chemicals! Pay attention to the order in which chemicals are to be added to each other and do not deviate from the instructions. Even chemicals that mix to produce seemingly safe products should be handled carefully. For example, hydrochloric acid and sodium hydroxide will give you salt water, but the reaction could break your glassware or splash the reactants onto you if you aren't careful!)7. Dress Appropriately (for chemistry lab, not fashion or the weather.)8. Read the Chemical Safety Information9. Do Not Pipette By Mouth.10. Take Data During Labhope it helped you !!
