Is homogeneous mixture between solute and solvent

Solution

Non electrolyte solution is the solution that

can’t to conduct electricity.

Non electrolyte compound is the compound

that can’t to ionized. Such as glucose, urea, and

alcohol.

For example:

Urea solution (CO(NH2)2 , alcohol solution

C2H5OH (ethanol), glucose solution (C6H12O6)

CO(NH2 )2(s) + water CO(NH2 )2(aq)

Non electrolyte solution

The comparison of electric conductivity the solution by using electrolyte tester

Electrolyte : Nonelectrolyte

solution

strong : weak electrolyte solution

Strong electrolyte : weak electrolyte: non electrolyte

The comparison between electrolyte and non electrolyte solution

The comparison between strong electrolyte and weak electrolyte solution

The comparison between strong electrolyte , weak electrolyte and

non electrolyte solution

Colligative properties are properties that depend only on the number of solute particles in solution and not on the nature of the solute particles.

Colligative Properties of Solutions

Lowering the Pressure Above the Solution (by opening bottle) Decreases Gas Solubility

1. How many grams of the nonelectrolyte sucrose (molar mass=342 g/mole) must be added to 450 g of water (molar mass=18.0 g/mole) to change its vapor pressure to 745 mm Hg at 100 oC? 

Dik : Mr sucrose = 342 g/mole Dit = g sucrose?

g of water = 450 g

Mr Water = 18.0 g/mole

P = 745 mm Hg

Jawab :

m

2. The vapor pressure of pure water (molar

mass=18.0 g/mole) at 50 oC is 92.5 mm Hg. A

solution containing the nonelectrolyte sucrose

(molar mass=342 g/mole) has a vapor pressure of

90.8 mm Hg at 50 oC.

a. What is the boiling point elevation of this

solution (Kb(water)=0.520 oC/m)?

b. If it has a density of 1.08 g/mL, what is the

osmotic pressure of this solution at 50 oC?

3. What is the freezing point of solution If

3.1 gram glicole (C2H6O2) dissolve in

250 gr water (Kf= 1.86 oC/m ) and mixed

with 17.1 gram of sucrose (C12H22O11)

into 500 gr of water?
