An unknown amount of sodium hydroxide (FW= 40) was dissolved in 500 mL distilled water before standardized using 0.4928 g of potassium acid phthalate (MW = 204.23) in 75 mL distilled water. Calculate the unknown amount of sodium hydroxide in gram if the standardization needs 25.3 mL of sodium hydroxide to achieve the titration end point and the stoichiometric reaction between sodium hydroxide and potassium acid phthalate is one mole to one mole. (Note: FW = formula weight, MW = molecular weight)

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?
