Calculate the expected pH-value of a TRIS buffer solution (at 23oC), which is prepared by mixing 25.0 ml of 0.100M hydrochloric acid with 25.0 ml of a 0.200M TRIS solution and then adding water up to 100 ml (at 23o C, pK is 8.13).
Problem- 15.0 mL of 0.50 M NaOH is added to a 100.-mL sample of 0.433 M NH3 (Kb for NH3 = 1.8x 10-5). What is the equilibrium concentration of NH4+ ions
