The solubility of benzoic acid in water is 6.80 g per 100 mL at 100 °C and 0.34 g per 100 mL at 25 °C. Calculate the minimum volume of water needed to dissolve 1.00 g of benzoic acid at 100 °C. Calculate the maximum theoretical percent recovery from recrystallization of 1.00 g of benzoic acid from 15 mL of water, assuming the solution is filtered at 25 °C. How much benzoic acid can you dissolve in 25 mL of...
Given the solubility of benzoic acid in water is: 0.68 g/100 mL @ 100 °C, and 0.34 g/100 mL at 25 °C. Calculate: a) Volume (mL) of water needed to dissolve 100 mg of benzoic acid at 100 °C. b) Weight of benzoic (mg) acid that remain soluble when the solution in part (a) is cooled to 25 °C. c) Recovery % of benzoic acid crystals that can be collected when the solution in part (a) is cooled to 25 °C.
The solubility of benzoic acid in water is 0.05 g/100 ml at 0oC and 7.87 g/100 ml at 100oC. Answer the following questions if 5.69 grams of benzoic acid were to be heated to boiling in 100 ml of water. What would be the maximum possible percent recovery in a second batch, if the mother liquor was reduced to 44.09 ml, chilled in ice water and vacuumed filtered? Put your answer in 3 significant figures.
Daisy Dominguez Solubility of Benzoic Acid in Water y = 1.479e9.0133 R-0.9955 20 40 A graph of temperature (°C) versus solubility of benzoic acid in water (g/L) has a good exponential fit, y = 1.479e0.0357x, indicated by the Goodness of Fit R? = 0.9955. Given that you used 19.9 ml of water to dissolve 0.786 g of benzoic acid, what was the actual temperature of your recrystallization setup according to this exponential equation? Don't forget that there are 1000 ml...
Solubility 5 mL of benzoic acid is titrated with 0.01M NaOH at 30.2oC. The titre volume obtained was 16.3 mL. The solubility of benzoic acid is calculated to be 0.0326 M. Calculate the solubility of benzoic acid in grams per 100 g of H2O at this temperature. Density of water at 30.2oC is 0.9955882 g/cm3
If the Partition Coefficient for Benzoic Acid in one mL each of Water and Methylene Chloride is 2.10, is there more Benzoic Acid in the Water layer or the Methylene Chloride layer? A) If you have one mL each of Water and Methylene Chloride in a vial, which layer is on the top? B) If the same experiment is repeated with benzoic acid between ether and water, which layer would be the top and which layer would be the bottom....
