Organic Chemistry
An impure sample contains 0.95g of benzoic acid and 0.05 of salicylic acid. Solubilities in water of the two compounds are given in the following table. Solubility at 20 degrees (g/10mL) benzoic acid: 0.029 salicylic acid: 0.22 Solubility at 100 degrees (g/10mL) benzoic acid: ...

The enthalpy of combustion of benzoic acid,C6H5COOH, which is often used to calibrate calorimeters, is -3227kJ/mol. When 1.236g of benzoic acid was burned in a calorimeter, the tempurature increased by 2.345K. What is the specific heat of the calorimeter?

How do I do a question like this please help and explain it!! Calculate the pH of a buffer solution that contains 0.22 M benzoic acid (C6H5CO2H) and 0.24 M sodium benzoate (C6H5COONa). [Ka = 6.5 10-5 for benzoic acid] Round your answer to two places past the decimal.

organic chemistry
1)Why benzoic acid is soluble in NaOH? 2)Why HCl is insoluble in titration of benzoic acid and NaOH? Benzoic is soluble in a solution of NaOH because the base forms the sodium salt with the acid to form sodium benzoate. The sodium salt is soluble. The second part of your ...
