please solve the hilighted Questions In Activity 1, what happened to the pH of the water sample as 0.1 M HCl was added? How did this compare to what happened with addition of one drop of 0.1 M HCl to each buffer solution? In Activity 1, why did the pH of the buffer solutions change after the addition of 10 drops of 0.1 M NaOH? NaOH is strong base when its added to the solution, its react with the weak...
Use activity coefficients to find the concentration of hydrogen ions in a solution of 70.0 mM butanoic acid (CH,COOH) and 0.1 M NaCl. The ionization constant of butanoic acid is k, = 1.52 x 10-5. Take the size of CH,COO to be 500 pm. Activity coefficients can be found in this table. [H] = 0.00103 What is the pH of this solution?
