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,H4NH3CI, 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 to be 7.1x10-3 while the base ionization constant of ethanolamine is 2.68x10-5
