1 KG SOLUTION - 10NORMALITYAMOUNT OF SOLUTE IN GRAMS/ 1 LITER SOLUTION
- 11MASS FRACTIONMASS OF COMPONENT/ TOTAL MASS OF SOLUTION
- 12SOLUBILITYMAX. AMT. OF SOLUTE DISSOLVED IN SPECIFIC AMT. OF SOLVENT AT A SPECIFIED TEMPERATURE
depends on temp., pressure and nature - 13SOLUBILITY OF SOLID IN LIQUID- like dissolves like
- 14DISSOLUTIONWHEN SOME OF THE SOLID SOLUTE IN SOLVENT DISSOLVES
- leads to increase in concentration of solute in solution - 15CRYSTALLIZATIONSOME SOLUTE PARTICLES IN SOLUTION COLLIDE WITH SOLID SOLUTE PARTICLES, THEY SEPARATE OUT
- 16WHAT HAPPENS WHEN DISSOLUTION AND CRYSTALLIZATION OCCUR TOGETHERWHEN BOTH PROCESSES OCCUR SIMULTANEOUSLY AT THE SAME RATE, A DYNAMIC EQUILIBRIUM IS ACHIEVED
PRESSURE AND TEMPERATURE ARE CONSTANT
CONCENTRATION IS CONCTANT - 17SATURATED SOLUTIONA SOLUTION IS SATURATED WHEN NO MORE SOLUTE CAN BE ADDED TO THE SOLUTION AT A PARTICULAR TEMPERATURE AND PRESSURE
- 18SOLUBILITY OF GAS IN LIQUIDINCREASES WITH INCREASE IN PRESSURE
AND DECREASE IN TEMPERATURE - 19HENRY'S LAWat constant temperature, solubility of gas in liquid is directly proportional to the partial pressure of solution
mole fraction of gas in solution is directly proportional to the partial pressure of gas in vapor phase - 20EQUATION FOR HENRY'S LAWP= K(h) x
where K(h) is Henry's law constant - 21HENRY'S LAW APPLICATION1) to increase CO2 in soft drinks, bottles are sealed in high pressure
2) scuba divers face 'bends' when they come to the surface. this occurs due to decrease in pressure, which releases dissolved gases and leads to formation of N2 bubbles in the blood - can block capillaries and cause zinc effect of N2
3) at higher altitudes, pressure of O2 is less - can lead to weakness, and inability to think clearly. this is called Anoxia - 22Vapour Pressurepressure exerted by vapour on surface of liquid at that temperature
- 23Raoult's LawFor a solution of volatile liquid, the partial pressure of each component is directly proportional to its mole fraction
p1= p1⁰ x x1
where p1⁰ is the vapour pressure of pure compound - 24Raoult's law for non volatilesif solution is non volatile, then the solute will not contribute towards total vapor pressure of solution
- 25SOLUBILITY OF LIQUID IN LIQUIDwe classify them into ideal and non ideal solutions
- 26IDEAL SOLUTIONSobey Raoult's law under all conditions of temperature and concentration
