50 grams of KCl are dissolved in 200 grams of water at room temperature. Is the resulting solution unsaturated, saturated, or supersaturated. Use the graph below

Arsenic acid is a triprotic acid with the pKa values pKa = 2.240, pK2 = 6.960, and pK 11.500. You wish to prepare 1.000 L of a 0.0100 M arsenate buffer at pH 6.380. To do this, you choose to mix the two salt forms involved in the second ionization, NaH, AsO, and Na, HASO,, in a 1.000 L volumetric flask and add water to the mark. What 4 mass of each salt will you add to the mixture? mass NaH, AsO, = mass Na, HASO, en
