III. Preparing HC,HO, Solutions and Determining pH only cal. One! theoretical pH 1.0 x 10-14 (181) concentration of HC,H,O, M
III. Preparing HC,H,O2 Solutions and Determining pH 2. Calculate the theoretical pH of each HC,H,O, solution, using Equation
Table 1 Some Weak Acids and their Ks acid chemical formula acetic butyric carbonic formic hypochlorous monohydrogen carbonate
pH = -log [H3O+] (Eq. 5) [H3O+] = 10-pH (Eq. 6) We can write similar expressions for (OH), shown in Equations 7 and 8 pOH = -
HCIO(aq) + H2O(l) = H3O+ (aq) + C10 (aq) (Eq. 10) In a weak acid solution, the relationship of [H3O+] to the acid equilibrium
