Solution

The correct option is B

Solubility of the solution is 25g/100g


Solubility:

  • The maximum amount of solute that can be dissolved in a specified amount of solvent at a specific temperature is known as solubility.
  • Once the concentration of solute is equal to its solubility, the solution is said to be saturated with that solute and the concentration stops increasing.

Here,200gramsofsolutioncontaining50gofsoluteSo,Massofsolvent(water)=Massofsolution-Massofsolute=200-50g=150gSolubilityofsolution=MassofsoluteMassofsolvent×100=50200×100Solubilityofthesolution=25%

Conclusion:

TheSolubilityofthesolution=25%.

Therefore, the correct answer is option B.
