1. Section 2 – Part 2 The Solution Process

2. By the end of this section you should be able to answer the questions:  What is the meaning of “like dissolves like”?  What is meant by miscible and immiscible?

3. Make some predictions. Will these solutes and solvents mix? oil and water? salt and water? syrup and water? syrup and oil? salt and oil?

4. Make some predictions. Will these solutes and solvents mix? oil and water? No, nonpolar and polar salt and water? Yes, ionic and polar syrup and water? Yes, polar and polar syrup and oil? No, polar and nonpolar salt and oil? No, ionic and nonpolar

5. This is a rough but useful rule for predicting whether one substance will dissolve in another. Polar and ionic compounds both have charge and will mix together. Nonpolar compounds do not have charges and so mix with each other. Polar/ionic and nonpolar do not mix.

7. Miscible – liquids that dissolve freely in one another in any proportion Immiscible – liquids that are not soluble in each other

8. Hydration – the solution process where water is the solvent Click here for video

9. What rule of thumb is useful for predicting whether one substance will dissolve in another? What is meant by the rule? Explain what is meant by miscible and immiscible.

10. What rule of thumb is useful for predicting whether one substance will dissolve in another? What is meant by the rule? Like dissolves like; nonpolar substances can dissolve each other and polar/ionic substances can dissolve each other Explain what is meant by miscible and immiscible. Miscible – two liquids that can mix Immiscible – two liquids that will not mix

11.  I CAN explain the meaning of “like dissolves like”.  I CAN differentiate between miscible and immiscible.
