Quantitative measure of a column’s ability to separate two solutes is called ---------------- a)Partition d)coefficient resolution c)dead time d)HETP

​

Answer 1

Answer:

I think partition is the best answer

Answer 2

The quantitative measure of a column’s ability to separate two solutes is called partition coefficient (option-a).

• Chromatography is a technique that is used to separate two or more components of a mixture.
• It consists of a mobile phase and a stationary phase.
• The mobile phase can be liquid in the state or gaseous in the state.
• The stationary phase can be a liquid or a solid.
• The mobile phase and stationary can be non-polar or polar in nature.
• In column chromatography, components of a mixture are separated on the basis of their polarity.
• On the basis of differential partitioning between the mobile phase and stationary phase, two solutes are separated.
• This ability of the column to separate two solutes is called the partitioning coefficient.
• It can be written as-

        Partitioning coefficient, K = concentration in stationary phase /   concentration in mobile phase
