A shipment of containing NaOH (40 g/mol) and Na2CO3 (106 g/mol) was declared to contain less than 10 % impurity. However, Noel is suspicious that the declared impurity is higher. Being the best and brightest employee of the year, Noel weighed 1.000 g sample, dissolved in 50.0 mL of distilled water and titrated with cold 0.5000 M HCl. With Phenolphthalein as indicator, the solution turns colorless after the addition of 30.00 mL of the acid. Methyl Orange is then added, and 5.00 mL more of the acid is required before this this indicator changes color. Calculate the following: a.

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)
