What happens to the concentration of a solution as more solute is added but the amount of solvent stays the same?

Question 3 options:

A. The concentration decreases

B. The concentration increases.

C. The concentration stays the same.

D. The concentration increases and then decreases.

B

Explanation:

More of what is to be dissolved is being added in, but the liquid doing the dissolving isn't increasing to make up for it.

i.e. too much drink mix powder added to water increases the taste versus too much water making the taste weaker

hydrocarbons are organic compounds that contain only hydrogens and carbons. they can be saturated (those which contain only carbon-carbon single bonds) or unsaturated (those which contain carbon-carbon double or triple bonds) in nature. hydrocarbons can undergo several reactions like substitution, elimination etc.  

on substituting one or more hydrogen atoms in hydrocarbon it results in the formation of haloalkane. as the halogen atoms are large compared to the carbon and hydrogen atoms, due to which the molecular weight increases and the bond become polar because of presence electronegative halogen atom and results in the increase in boiling point of the haloalkane.

thus, the correct option is (b) that is the boiling point of the new compound increases on substituting a hydrogen atom with a halogen in a hydrocarbon.
