Paper chromatography is a laboratory technique that is used to
1. separate different molecules from one another
2. stain cell organelles
3. indicate the ph of a substance
or 4. compare relative cell sizes

Answer : The correct option is, (1) separate different molecules from one another.

Explanation :

Paper chromatography : It a type of separation process in which the liquid or gas molecules are separated  from one another at different rate.

The principle of paper chromatography is that the substance of molecule are distributed between the liquid phases. As we know that they all have a stationary and mobile phase. In this, one phase (stationary phase) is water that is held in the pores of filter paper and other is mobile phase which moves on the paper.

Hence, the paper chromatography is a laboratory technique that is used to  separate different molecules from one another.

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
