Answer:
B = water molecules surrounded solute molecules.
Step-by-step explanation:
Solvent:
Solvent is the that part of solution which is present in large proportion and have ability to dissolve the solute.
Step-by-step explanation:
In simplest form it is something in which other substance get dissolve. The most widely used solvent is water, other examples are toluene, acetone, ethanol, chloroform etc.
The solvent dissolve the solute. The dissolution of solute in to solvent always follow the " like dissolve like " rule of chemistry.
If solvent is made up of polar substance then it dissolve the polar solute. If it is non polar then it can dissolve the non polar substances.
Example:
when polar substance such as sodium chloride dissolve in water the sodium chloride dissociate into ions. The sodium becomes Na⁺ and Cl⁻ becomes negative ions. The partial positive charge of water i.e, H⁺ surrounded the Cl⁻ and partial negative charge of water i.e, OH⁻ surrounded the Na⁺ and NaCl gets dissolved.
