2 A ionizes as shown below. Calculate the pH of 0.15 M NaCN solution. Aqueous solutions of one of the following is acidic. Calculate the pH of a solution that is 0.10 M in acetic acid and 0.30 M in sodium acetate. A solution that is 0.20 M in NH 3 is also 0.30 M in NH 4 Cl.
Aniline ionizes as follows.
I. A buffer solution could consist of equal concentrations of ammonia and ammonium bromide. A buffer solution will change only slightly in pH upon addition of acid or base. Calculate the pH for a buffer solution prepared by mixing 100. The nonionized form of an acid indicator is yellow, and its anion is blue. The predominant color in its acid range is yellow.
