Heterogeneous mixture Particles of varied size

Page 3: Solutions The story continues. Heterogeneous mixture Particles of varied size

Heterogeneous mixtures Suspension – Particles settle out if left

alone Colloids – Based on size of particles and

the action of solution (477 table 1)

Page 4: Solutions The story continues. Heterogeneous mixture Particles of varied size

Homogeneous mixtures You cannot see various parts of the

solution. (479 table 2)

Page 5: Solutions The story continues. Heterogeneous mixture Particles of varied size

Concentration Compares the amount of solute that is

in a solvent

Many ways to express this…

Page 6: Solutions The story continues. Heterogeneous mixture Particles of varied size

Concentration Percent by mass

% by mass = (mass solute/mass solvent)*100

Page 7: Solutions The story continues. Heterogeneous mixture Particles of varied size

Concentration Percent by volume

% by volume = (volume solute/volume solution)*100

Page 8: Solutions The story continues. Heterogeneous mixture Particles of varied size

Concentration Molarity

Molarity = (moles solute/liters solvent)

Solubility of a gas Depends on:

Temperature Pressure

Higher pressure “Pushes” molecules into the solution

Solubility of a gas The solubility of a gas is .35 g/l at S.T.P.

What is the solubility of the material if the pressure is reduced to .75 atm?

Page 22: Solutions The story continues. Heterogeneous mixture Particles of varied size

Solubility of a gas At 25°C and 1 atm, 1 g of a gas

dissolves in 2 L of water. What mass of the same gas will dissolve in 2 L of water at 25°C and 4 atm?
