What term is used by chemist to quantitatively describe a solution in which a relatively small amount of solute is dissolve?
Dilute
What Contains the maximum amount of dissolved solute for a given amount of solvent at a specific temperature and pressure?
a saturated solution
Is dilution is the addition of solute to decrease the concentration of solvent?
No. dilution is the addition of solvent to decrease the concentration of a solute.
What are the 4 factors that affect the solubility of solute?
The solubility is affected by: 1. the nature of solute/solvent (chemical composition, polarity) 2. temperature 3. pressure 4. stirring 5. surface area of the solute 6. some added compounds 7. amount of the solute 8. the geometry of the beaker
What are the factors on which rate of dissolving a solute in a solvent depends?
Temperature, pressure, the amount of the solute surface area exposed to the solvent and the saturation point of the solvent are some of the factors.
What changes will decrease the total amount of gaseous solute able to be dissolved in a liter of liquid water?
decrease in pressure
What term is used by chemist to quantitatively describe a solution in which a relatively small amount of solute is dissolve?
Dilute
What are the properties of a colligative property?
1. Vapor pressure lowering: the decrease in vapor pressure with increasing the number of solute molecules in solution. 2. Boiling point elevation: the increase in boiling point with increasing number of solute molecules in solution. 3. Freezing point depression: the decrease in freezing point with increasing number of solute molecules in solution. 4. Osmotic pressure
How can you increase the solubility of a gaseous solute?
Decrease the temperature, if aqueous. Increase the pressure.
What do you need to do to a concentrated solution to make it weaker?
You can dilute it by adding more solvent. Many solutions are in water. Therefore, adding more water will decrease the concentration. C = n/v Concentration is inversely proportional to volume and directly proportional to the amount of solute. An increase in volume or a decrease in the amount of solute, will decrease concentration.
What are the three properties of a solution?
1. Vapor pressure lowering: the decrease in vapor pressure with increasing the number of solute molecules in solution. 2. Boiling point elevation: the increase in boiling point with increasing number of solute molecules in solution. 3. Freezing point depression: the decrease in freezing point with increasing number of solute molecules in solution. 4. Osmotic pressure
What Contains the maximum amount of dissolved solute for a given amount of solvent at a specific temperature and pressure?
a saturated solution
Is dilution is the addition of solute to decrease the concentration of solvent?
No. dilution is the addition of solvent to decrease the concentration of a solute.
What are the three factors affecting how a given amount of solute will dissolve in a given amount of solvent?
The factors effecting the creation of a solution are: temperature, pressure. and the amounts and relative natures of the solute and solvent.
What is the concentraction of the solution?
Concentration is the amount of a solute in a given volume of solution at a given temperature and pressure.
For the chemist a concentrated solution has?
little solvent and much solute r.s.c
What are the 4 factors that affect the solubility of solute?
The solubility is affected by: 1. the nature of solute/solvent (chemical composition, polarity) 2. temperature 3. pressure 4. stirring 5. surface area of the solute 6. some added compounds 7. amount of the solute 8. the geometry of the beaker
