Explain the term of Solute.
How are sol, solution and suspension different from each other?
Explain how the following factor affects the formation of a solution is proportion of the solute & the solvent.
Define the term ‘solubility ’ of a solute in water. If 10 g. of a solute is added to 100 g. of water at 50°C and stirred, it is seen that the total solute dissolves at that temperature giving an unsaturated solution. Is 10 g, the solubility of the solute in water. Give reasons.
How are solutions generally classified. What is the basis of this classification.
Draw a table to differentiate – True solutions, colloidal solutions & suspensions – with respect to
