  1. The conjugate base of a strong acid is a weak base and vice versa. We can use the relative strengths of acids and bases to predict the direction of an acidbase reaction by following a single rule: an acidbase equilibrium always favors the side with the weaker acid and base, as indicated by these arrows:

  2. Weak bases. Explaining the term "weak base" Ammonia is a typical weak base. Ammonia itself obviously doesn't contain hydroxide ions, but it reacts with water to produce ammonium ions and hydroxide ions. However, the reaction is reversible, and at any one time about 99% of the ammonia is still present as ammonia molecules.

  3. When a weak acid and a strong base are mixed, they react according to the following net-ionic equation: HA(aq) + OH⁻(aq) → A⁻(aq) + H₂O(l). If the acid and b...

  4. Sep 27, 2022 · HClO 4. Ca (OH) 2. Sr (OH) 2. Ba (OH) 2. The issue is similar with bases: a strong base is a base that is 100% ionized in solution. If it is less than 100% ionized in solution, it is a weak base. There are very few strong bases (Table \ (\PageIndex {1}\)); any base not listed is a weak base. All strong bases are OH – compounds.

  5. Jan 7, 2011 · pH. An acid dissociates into H + in solution according to: HA → H+ + A-. The stronger the acid, the greater the concentration of H+ and therefore the lowerthepH. pH value of a strong acid & base table. The most accurate way to determine the pH is by reading it off a pH meter. The pH meter is connected to the pH electrode which shows the pH ...

  6. May 12, 2014 · Therefore, we conclude that if one has a strong acid, then its conjugate base must be weak. The converse is also true; if an acid's conjugate base is weak, then the acid must be strong. The first equation you wrote is a neutralization reaction, if seen as a reverse reaction.

  8. May 30, 2020 · First, let reactions go to completion (in the direction that makes sense, i.e. weak base and strong acid forms weak acid and spectator ion - never the other way around). Then, check what the major species are and estimate the pH. Finally (and this step is often omitted), see if equilibria involving minor species (such as hydroxide for acidic ...
