Write a balanced equation for the dissociation into ions of each of the following soluble salts in aqueous solution. (Use the lowest possible coefficients. Omit states of matter.) RbNO3 Al2(SO4)3

11. TAPS is the acronym of ((tris(hydroxymethyl)methylamino)propanesulfonic acid), which is a chemical compound commonly used to make buffer solutions. A TAPS buffer solution is prepared by mixing 2 solutions. The first solution is 200.0 mL and it contains 52.661 grams of TAPS. The buffer solution is prepared by adding 51.92 mL 0.9832 M KOH solution to the first solution. Assume that the volume is additive. At 25 °C, the pKa of TAPS is 8.441. C7H₁7NO6S + KOH → C₂H₁6NO6SK + H₂O Determine the equilibrium concentration of TAPS in the buffer solution. Please provider your answer below. A. B. Determine the equilibrium concentration of C7H16NO6SK in the buffer solution. Please provider your answer below. f $ + $ Determine the pH of the buffer solution. pH = Please provider your answer below. $ M M
