Solubility tests of benzoic acid with a dissolution enthalpy of -32kJ / mol were performed at 2 different temperatures. In the first experiment carried out at 27 ° C, 5 mL of the sample taken from the benzoic acid solution is taken into 25 mL of water and titrated with 0.02M NaOH. As a result of the titration, there is 8 mL consumption, respectively. In the second experiment performed at a different temperature under the same conditions, 22 mL was consumed. Taking advantage of these results a) What is the solubility of benzoic acid at 27 ° C? b) What is the solubility of benzoic acid at different temperatures? c) What is the second test temperature? (M (benzoic acid): 122.12 g / mol)
