Calculate the pH of a 5.2 x 10-2 M solution of sodium benzoate in otherwise pure water at 25oC. For benzoic acid, Ka = 6.5 x 10-5 .
What mass of sodium benzoate (NaC6H5COO, MM = 144.11 g/mol) is required to create a 125. mL buffer with 1.30 M benzoic acid (C6H5COOH, Ka = 6.3 * 10-5) that has a pH = 3.75? Calculate your answer in grams. Round to one decimal place and only input the number value. (Do not add a unit.)
What will be the new value of the pH if 20.0 g of solid sodium benzoate (C6H5COONa) is added to 1.0 L of 0.30 M benzoic acid (C6H5COOH(aq)) solution and all the solid dissolves without a change in volume of the solution? The KA of benzoic acid is 6.6 x 10 -5.
Question 2 What mass of sodium benzoate (NaC6H5COO, MM = 144. 11 g/mol) is required to create a 125. mL buffer with 1.30 M benzoic acid (C6H5COOH, Ka = 6.3* 10-5) that has a pH = 3.75? Calculate your answer in grams. Round to one decimal place and only input the number value. (Do not add a unit.)
Equal volumes of 0.272 M aqueous solutions of hydrofluoric acid (HF(aq)) and sodium benzoate (NaC6H5COO) are mixed. (1) Write the net ionic equation for the overall reaction that takes place as the system comes to equilibrium. Write acetic acid, benzoic acid or formic acid and their conjugates in the form RCOOH / RCOO-. For example, benzoic acid should be written "C6H5COOH" NOT "C6H5CO2H". It is not necessary to include states such as (aq). ________ + _________ ----> __________ + __________...

Calculate the pH of a buffer solution that contains 0.25 M benzoic acid (C6H5CO2H) and 0.15 M sodium benzoate (C6H5COONa). (Ka = 6.5 x 10-5 for benzoic acid)
calculate the pH of a 0.30 M solution of benzoic acid (HC7H5O2, Ka = 6.5x10-5)
A buffered solution with pH of 4.4 is made of 0.1 M Benzoic acid, HC-HOs, and 0.15 M Sodium benzoate, NaC;HO2. After an addition of 1.5 mLs of 6.0 M HCI to 250 mLs of the buffered solution, what is the resulting pH? Ka 6.6 x 10
