please explain 1. Why is the conjugate base of aspirin more soluble in water than...
Compound A is three times more soluble in diethyl ether than in water, so its partition coefficient is K = 3, for partitioning of Compound A between diethyl ether and water. for a sample of compound a dissolved in 50mL of water, answer the questions: 1) Determine the fraction of A that remains in the water, FA, after one extraction with 200mL of diethyl ether. 2) Determine FA after two extractions, using 100mL of diethyl ether in each of the...
6. Draw the conjugate acid of phenetidine and explain why it is highly soluble in water. Make sure to reference any relevant intermolecular forces as part of your answer. 6b. The solubility of dulcin in water is 1.21 g/L at room temperature. Assuming that you added a total of 82.5 mL of water between the reaction setup and the recrystallization process, how much dulcin (in mg) would remain in solution after recrystallization if you allowed the flask to cool to...

please help >< Polyprotic acids have more than one proton to donate to water, therefore have more than one equilibrium constant for proton donation. For phosphoric acid, there is a three-step equilibrium: H, PO +H,0 5 H2PO4 + H30* H,PO," +H,0 5 HPO - +H30* HPO 2- +,0 5 PO.- +,0* Kai = 7.11 x 10-3 Ka2 = 6.32 x 10-8 Ka; = 4.5 x 10-13 For all conjugate acid base pairs: K, XKK where K is for the reaction...
