One synthetic preparation of aniline involves reducing nitro benzene with iron and HCL, and then steam distilling the resultant aniline at 99 degrees Celsius. How much aniline codistills with each gram of water during the steam distillation.
Consider the galvanic cell with Sn2+/Sn and Ag+/Ag both prepared with NO3- as their anion and all solutions prepared at 1.0 M. What is the overall reaction and what is the oxidation half-reaction? Does it occur at the anode or cathode
Calculate the hydronium concentration for a solution prepared by dissolving 0.15 mol of benzoic acid (C6H5COOH) and 0.30 mol of sodium benzoate (C6H5COONa) in 1.00 L of solution. (Ka of C6H5COOH = 6.5 x 10-5)
