pH = -log[H?O?] pOH = -log[OH?] pH + pOH = 14 K? = [H?O?][OH?] K? = 1.0 × 10?¹? 3. For each reaction below, label each reactant as acid or base, label each product as conjugate acid or conjugate base and list the two conjugate acid-base pairs: PLAN: The acid donates a proton (H?) to form its conjugate base; the base accepts a proton to form its conjugate acid. Every acid has a conjugate base, and every base has a conjugate acid. The acid has one more H and one more positive charge than its conjugate base. A. HBr(aq) + HS?(aq) ? H?S(aq) + Br?(aq) B. HClO(aq) + CH?NH?(aq) ? CH?NH??(aq) + ClO?(aq) 4. Give the conjugate bases of the following acids: PLAN: Remove H? from each acid to get the conjugate base: the charge becomes more negative since you are removing a +1 charge. The charge of the species is important, so don't omit it! a. HNO? b. HPO?²? c. HCOOH

          pH = -log[H?O?]
pOH = -log[OH?]
pH + pOH = 14
K? = [H?O?][OH?]
K? = 1.0 × 10?¹?
