Which of the following situations is most favorable for solubility? View Available Hint(s) Which of the following situations is
2 answers:
Answer: Option (a) is the correct answer.
Explanation:
It is known that more is the attraction between molecules of a solute with the solvent molecules then more attraction takes place. Due to this more number of solute particles will dissolve in the solvent.
For example, NaCl is an ionic compound and water is a polar solvent. So, when we dissolve NaCl (solute) in water (solvent) then sodium chloride will completely dissolve in water because like dissolves like.
This also means that due to the strong attraction between NaCl molecules and water molecules the salt dissociates into and
ions.
Thus, we can conclude that out of the given options strong attraction between solute particles situation is most favorable for solubility.

The substance that conducts electricity is dissolved in water.
So, option A is correct one.
When the sodium chloride dissolve in water , the sodium atoms and chlorine atoms separates under the presence of water molecules and exist as sodium cation and chloride anion . Now , they are free to move around in the water as positively and negatively charged ions . This separation of charge allows the solution to conduct electricity.
The solid and solid sugar does not conduct electricity because it is not dissolve in water . Similarly, sugar dissolved in water does not conduct electricity .
