Basic of solutions

Question 1

What is solution?

Answer 1

Homogenous mixture of 2 or more compounds

Question 2

What does solubility of solid compound ( ionic ) depends on?

Answer 2

Hydration energy and lattice enegry

Question 3

In order to form solution, IMF between solvent solute must stronger than….

Answer 3

solvent - solvent and solute - solute

Question 4

Solvent surround solute or Solute surround Solvent?

Answer 4

Solvent surround solute

Question 5

Explain about hydration energy and lattice energy in solution

Answer 5

+ve part of solvent attracted to anion of solute
-ve part of solvent attracted to cation of solute

Question 6

What happen when Hydration energy > Lattice energy?

Answer 6

Anions and cations uniformly distributed in solvent

Question 7

What is solubility?

Answer 7

maximum amount of solute dissolve in given amount of solvent at specified temperature

Question 8

How many types of solution?

Answer 8

• Unsaturated
• Saturated
• Supersaturated

Question 9

What happen in unsaturated solution?

Answer 9

rate of dissolution> rate precipitation
[ solute in solution ] < solubility

Question 10

What happen in saturated solution?

Answer 10

rate dissolution= rate precipitation
[ solute in solution ] = solubility
equilibrium reached

Question 11

What happen in supersaturated solution?

Answer 11

[ solute in solution ] > solubility
unstable
