Describe the preparation of 1L solution of 0.02M Tris buffer, PH 7.8. Please don't just write numbers.. explain it.
a liter of solution contains 0.140 M Ca+2 and 0.140 M Pb+2. They are to be seperated using chromate (CrO4-2) to selectively precipitate out one metal.
Calculate the pH of a 100.0 mL buffer that is 0.158 M HClO and 0.099 M NaClO after adding 1.0 mL of 5.9 M NaOH solution. (Ka for HClO given at 2.9*10^-8 and assume the volume change of added NaOH solution is negligible)
