benzoic acid has PKa of 4.2 and MW 122g/mol. sodium benzoate has MW 144g/mol . a) mixing 50 grams of benzoic acid with 50 grams of sodium benzoate will lead to the same PH as mixing 200 grams of each. How do they differ in buffer capacity?B) could benzoic acid/ benzoate act as a buffer at PH 6.0? why or why not?C) what concentration of benzoic acid and sodium benzoate should be used to prepare a buffer that has a...
