The solvent quantity is much lower because the overall solubility of the compound is much higher, but due to the low slope of the curve, the recovery is very poor. Sound like when you played the cassette tape with programs on it {. Now if you want to know the purity, you'll need to do the same with both of your component to see how much of them have cristalised at the end and then determine the purity of your marjoritory compound. Since most reactions do not go to completion or afford byproducts, the crude product is more or less contaminated with other compounds. The percent recovery in recrystallization is usually less than 100% (although sometimes it can be 100% or larger, see the next problem). a) Calculate the minimum volume of water needed to dissolve 1.00 g of benzoic acid at 100 degrees Celsius 100ml/68g=14.7 ml water b) Calculate the maximum theoretical percent recovery from the recrystallization of 1.0 g of benzoic acid from 15 mL of water, assuming the solution is filtered at 25 degrees. Notice that $\frac{m_A^\mathrm{i}}{m^\mathrm{t}}=x_{A,\mathrm{i}}^\mathrm{liq}$ which is the mass-fraction at the begining in the liquid and $x_A^\mathrm{liq}$ is the mass-fraction in the liquid at the end. $('#mce_tmp_error_msg').remove(); The sample contains some percent A and some percent B with A being the majority.
