25. Consider a system that includes both the Al(OH)3(s) (Ksp = 3 x 10-34) and the complex ion [Al(OH)4]- (Kf = 3 x 1033). What would be the effect of decreasing the pH of the solution? A. The mass of Al(OH)3 would increase. B. The concentration of [Al(OH)4]-would increase. C. The concentration of [OH-] (aq) would increase. D. Adjusting the pH would not impact the concentration of any of the species in solution. The answer is A, but can youp lease help explain why this is true? Thanks!
1. How do you prepare a 100mL of 0.1 M phosphate buffer?To make 100 mL of 0.1 M phosphate buffer: Calculate the amount of sodium phosphate needed. moles of sodium phosphate = (0.1 mol/L) x (0.1 L) = 0.01 moles mass of sodium phosphate = moles x molar mass = 0.01 moles x 142 g/mol = 1.42 g Dissolve 1.42 g of sodium phosphate in distilled water in a 100 mL volumetric flask. Adjust the pH of the solution to the desired value (usually around 7.4) using a strong acid or strong base. Bring the solution to the final volume (100 mL) with distilled water. 2. From the anterior buffer, how do you make 100mL of 0.05 M?
