4. Two RND Engineers were assigned to create buffer solutions for two separate product lines that were susceptible to degradation if their pH was not maintained at a certain level. [a.] Engr. Baylon prepared the buffer for the product that requires a pH of around 4.0 by mixing 0.225 M of phosphoric acid and 0.414 M of sodium dihydrogen phosphate [b.] 0.640 M of ethanolamine, HOC,H,NH, were mixed with 0.750 M of its chloride salt, HOC,H¼NH3CI, by Engr. Samonte for the alkali goods that requires a pH of 9.5 max. Are the prepared buffers solutions applicable for their intended use? Take the acid ionization constant of phosphoric acid of ethanolamine is 2.68x10-5 be 7.1x10-3 while the base ionization constant

Calcium Benzoate: a) A sample of saturated CaBz2 solution is at equilibrium. The initially-prepared concentrations are [Ca?+]; = A and [Bz]; =B. This sample is allowed to saturate, and then the remaining solid is filtered out. As determined by titration, the final benzoate ion concentration in solution is [Bz]:= C. What is the solubility product of CaBz2, in terms of A, B, and C?| b) In our lab experiment, the CaBz2 solution is saturated at equilibrium before titration. Why must the CaBz2 solutions be saturated?
