Consider the following unfinished table of weak acids with their corresponding pKa values and Ka values. Weak Acid pKa Ka HNO2 3.35 -- HF -- 6.8 % 10^-4 HCN 9.31 -- Arrange these three acids in order of increasing acid strength. a. (weakest) HNO2 < HF < HCN (strongest) b. (weakest) HCN < HF < HNO2 (strongest) c. (weakest) HCN < HNO2 < HF (strongest) d. (weakest) HF < HNO2 < HCN (strongest) e. (weakest) HNO2 < HCN < HF (strongest)

Consider the three acids below and their Ka values. Answer the following questions: Which of the acids is the strongest? Which of the acids is the weakest? Which acid has the strongest conjugate base? Complete the table with pKa values. Acid HCOOH HCN HCIO Ka 1.8*10^(-3) 1.7*10^(-6) 1*10^(-4) pKa Complete the table [H0^(-) [OH^(-)] pH pOH Acidic or Basic

Several acids are listed here with their respective equilibrium constants. $$\begin{aligned} &\mathrm{HF}(\mathrm{aq})+\mathrm{H}_{2} \mathrm{O}(\ell) \rightleftarrows \mathrm{H}_{3} \mathrm{O}^{+}(\mathrm{aq})+\mathrm{F}^{-}(\mathrm{aq})\\ &K_{\mathrm{a}}=7.2 \times 10^{-4}\\ &\mathrm{HPO}_{4}^{2-}(\mathrm{aq})+\mathrm{H}_{2} \mathrm{O}(\ell) \rightleftharpoons \mathrm{H}_{3} \mathrm{O}^{+}(\mathrm{aq})+\mathrm{PO}_{4}^{3-}(\mathrm{aq})\\ &K_{\mathrm{a}}=3.6 \times 10^{-13}\\ &\mathrm{CH}_{3} \mathrm{CO}_{2} \mathrm{H}(\mathrm{aq})+\mathrm{H}_{2} \mathrm{O}(\ell) \rightleftharpoons \mathrm{H}_{3} \mathrm{O}^{+}(\mathrm{aq})+\mathrm{CH}_{3} \mathrm{CO}_{2}^{-}(\mathrm{aq})\\ &K_{\mathrm{a}}=1.8 \times 10^{-5} \end{aligned}$$ (a) Which is the strongest acid? Which is the weakest acid? (b) What is the conjugate base of the acid HF? (c) Which acid has the weakest conjugate base? (d) Which acid has the strongest conjugate base?
