what makes a good crystallization solvent
Give this one a try later!
-can dissolve large quantity of product at HIGH TEMPERATURE
-not dissolve the product at LOW TEMP
- dissolve impurities at ALL TEMP
-doesn't react with product
, principle of Recrystallization theory
Give this one a try later!
solubility or a compound usually increases with increased temperature of
the solvent (solubility depends on concentration, polarity, and
temperature)
Volumetric Analysis
Give this one a try later!
titrimetric, precision--quantitative analysis
disadvantages: time consuming and expensive
ppm
Give this one a try later!
mass of solute/mass of solution * 10^6
Spectroscopic Methods
Give this one a try later!
colorimetric analysis "Beer's Law" precision, semi quantitative, blank
solution for control
advantages: rapid, east to establish quality control, measures for reliability
