theyre all one problem. please help me answer every single one! 3. Salicylic acid was used as a pain reliever but it was hard on person's stomach. Aspirin is easier on a person's stomach. HO. HO. HO. salicylic acid pKa = 2.98 aspirin pKa = 3.5 a. You do an equilibrium calculation to calculate the pH of a 0.1 M aspirin or salicylc acid solution. I would use equation to calculate [H+] in this solution (C = concentration of acid solution). The [H+] in the aspirin solution isthan the [H+] in the salicylc acid solution because aspirin is a acid than salicylc acid. Ka = (C)/(x)(x) (blank 1) Ka = x/C-x (blank 1) Ka = (C-x)(C-x)/(x) (blank 1) Ka = (x)(x)/(C) (blank 1) Greater than (blank 2) Less than (blank 2) Equal to (blank 2) stronger (blank 3) weaker (blank 3) same (blank 3) 口ロ口
