solutions Flashcards
1
Q
effect of temperature on solubility
A
exothermic process- solubility decrease with increase in temperature
endothermic=solubility increase with increase in temperature
pressure -no effect
2
Q
solubility of a gas in liquid
A
temperature same as a solid case
the partial pressure of gas in the vapour phase is proportional to the mole fraction of gas in solution
p=kh.x where kh is henry constant
3
Q
concentration terms
A
1.mass percentage (W/W) = mass of solute/total mass of solution *100
4
Q
A
- molarity = number of moles of solute/
volume of solution in L
5
Q
A
- molality = number of moles of solute/
weight of solvent in kg
6
Q
A
- normality= number of gram equivalents/
volume of solution in L
7
Q
A
ppm= number of ppm of solute/
total number of parts of components of solution *(100)
