Weak Base Equilibrium (continued)

Weak Base Equilibrium (continued)

Weak Base Equilibrium (continued). HA H + + A -. HCN H + + CN -. Every weak acid has a corresponding weak conjugate base. eg:. Here, HA is a weak acid, and A - must be a weak base. (it also happens to be the conjugate base of HA).

Weak Acid – Strong Base Titrations

Weak Acid – Strong Base Titrations

pH curve for CH 3 COOH titrated with NaOH. pH at equiv. pt. 7. pH. B. mL of NaOH added. A. Weak Acid – Strong Base Titrations. The equivalence point is when, say, 50.0 mL of 0.10 M NaOH have been added to 50.0 mL of 0.10 M CH 3 COOH, but pH is > 7 at that point because.

Weak Acid + Strong Base Titration

Weak Acid + Strong Base Titration

Weak Acid + Strong Base Titration. There are two key points in a titration process. Equivalence Point – the point in the titration when the moles of added base (OH - ) are equal to the moles of acid in the original sample. Equimolar acid and base species.

Weak acid and base calculations

Weak acid and base calculations

Weak acid and base calculations. What’s so hard?. Unlike strong acids and bases, weak examples do not dissociate fully. For example, a 1 molL -1 HCl solution dissociates fully, so we make the approximation that the [H 3 O + ] = 1 molL -1.
