What else can I help you with?
Why was it necessary to avoid splashing the liquid solvent on the sides of the beaker in chromotography?
Splashing the liquid solvent on the sides of the beaker could introduce impurities into the sample or cause uneven migration of the compounds being separated. This could result in distorted or inaccurate separation patterns during chromatography.
Why we pour acids in test tube along its wall?
To avoid splashing.
Why bumping granules never be added to a solution which is already boiling?
To avoid splashing.
Why should bumping granules be used when boiling liquids?
To avoid splashing of liquids.
What are porcelain chips for?
Porcelain chips are used to avoid splashing during boiling of liquids.

What is the normal boiling chips in the distilling task?
To avoid overpressure and splashing during boiling.
Why do you need to cover the beaker with a lid during paper chromatography?
During the development of a chromatogram, it is better to cover it with a beaker to prevent evaporation, which will affect the movement of the solute and solvent system. This will ensure that the chromatogram will develop properly.
Why do we add boiling chips to the cold liquid before boiling?
The motivation is to avoid uncontrolled boiling and splashing.
How can bumping be avoided when water is being heated in a beaker?
in order to minimize liquids bumping effect during boiling, the container should be uncovered so that the atoms would have enough space to move. During boiling, the atoms react to heat causing the increase motion.
What safety precautions must be taken when handling acids?
- work in a hood - work with gloves and protection glasses - avoid splashing - avoid contact with eyes, skins, clothes - avoid inhalation and ingestion
How do you Pour Acid?
When handling acid, wear appropriate protective gear including gloves, goggles, and an apron. Always pour acid slowly and carefully to avoid splashing. Pour the acid from a container held close to the target container to minimize spills and ensure accurate pouring.
