WebMar 6, 2014 · The molarity becomes the [H+] concentration of 3.2 × 10−3. We know this is the [H+] concentration because HNO3 is a strong acid, since the acid will completely dissociate into H+ and NO− 3. To find the pH calculate −log[H+] −log[3.2 × 10−3] = 2.49 = pH. To find the pOH take the pH value and subtract it from 14. 14 −2.49 = 11.51 = pOH. WebFeb 12, 2001 · The equilibrium associated with K1, can be considered to be negligible in its effect on subsequent calculations only if the sample is collected correctly and if field temperature and field pH measurements are made
WebSolution. The Ka for oxalic acid is. K a = 1 E − 14 1.8 E − 10 = 5.6 E − 5. DIscussion. The calculation regarding Ka and Kb conversion is simple, but understanding what problems require this type of conversion is difficult. The concept is rather useful, and it further broadens the concept of acid and base. WebTo convert Ka into pKa, get out your calculator and find -log, then open bracket, Ka value, close bracket.
