Lecture 19 Neutral Territory: Acid-Base Reactions Key Idea: Acids react with bases such that the products are relatively weaker acids or bases or neutral. Reactions between strong acids and bases HCl (aq) + NaOH (aq) ! NaCl (aq) + H 2 O (l) HNO 3 (aq) + NaOH (aq) ! NaNO 3 (aq) + H 2 O (l) Ca(OH) 2 (s) + 2 HCl (aq) ! CaCl 2 (aq) + H 2 O (l) HNO 3 (aq) + HCl (aq) ! no reaction Ca(OH) 2 (s) + NaOH (aq) ! no reaction Acid plus bases gives salt plus water. Net ionic equation: H 3 O + + OH - ! 2 H 2 O Predict the products. For a stoichiometric reaction, what is the pH of the resulting solution? Reactions between weak and strong Predict the products. CH 3 COOH (aq) + OH - (aq) ! NH 4 + (aq) + OH - (aq) ! F - (aq) + H 3 O + (aq) ! HCO 3 - (s) + H 3 O + (aq) ! You have used titrations in lab to determine the amount of acid in a solution. What happens in the titration solution? How does the [H
