The eluting strength of a solvent is primarily related to how strongly it adsorbs onto the adsorbent and because typical adsorbents are highly polar; thus, eluting strength increases with solvent polarity.
Explanation:
The polarity of a solvent makes it more suitable for elution in a polar adsorbent. Hence the choice of solvents should be in order of increasing rather than decreasing polarity. polarity must increase and not decrease
If liquid bromine is cooled to form a solid, which type of solid does it form? Brass is made by melting copper and zinc and physically mixing them. As this alloy is cooled, it forms a solid where the copper and zinc are not chemically bonded together.
