Question

7. What do you know about intermolecular force and intramolecular force? Can you describe each force? What properties that could give information regarding the intermolecular forces from macroscopic measurements? 8. How do you describe the conditions which are called unsaturated, saturated and supersaturated solution? How is the relation of Solubility (s) with the solubility product constant (Ksp)? 9. Why the solubility of ionic solutions depends on the temperature? explain the reasons.

Answer 1

Solution Unsaturated Solution: An unsatura lution: An unsaturated Solution can capable of dissolving more Solute. It is condition of the solution which we can keep adding the Slute in this. It has the ability to make that Slute to dissolve. That is less solute than saturated solution at given Temperature Saturated Solution. In this solution we cannot dissolve any more solute. In see turated Solution all the solute is dissolved and it looks like Unsaturated Solution. But we add more Solute in it this will result in undissolved particles. This Condition g solution so called Saturated Solution. Here maximum Solute at that given temperature Super Saturated Solution: In this Super Saturated solution more amount of Solate can dissolve that Saturated Solution by increasing the temp of the Sutunated Solution. and thus the super saturated Solution can be achieved

Solution 2. Relation between Solubility (s) and Solubility product constant (Ksp) • Suppose thad the Solubility g a sparingly Soluble salt Ax By is 's moles I litere, there we have 9+ 2 Ax By XA at y B" This is dissociated Ax By 's moles x A4 - (xs) moles (48) - (ys) moles then we can say that concentration is equaiolent to as [A +] = us moles A to the pare left) And moles [B*] - gs moles Ksp = [437* [*: 79 = [xs) (ys)

3 Why the the solubility of temperature o sxplain ionic the Solution reasons. depends on Solution : This is because komperature has a direct effed on solubility. In jonic solution as temperature increase the solubility also increases. The reasons behind this is a temperature increases more amount e particles of the Solid move faster. and the Solute posticle interact with the Silvend particles and then the sale of Solubility increases.
