WebNov 28, 2024 · a pH = pK + log ( [A-]/ [HA]) [A -] = molar concentration of a conjugate base [HA] = molar concentration of an undissociated weak acid (M) The equation can be rewritten to solve for pOH: pOH = pKb + log ( … WebNow, for the pH of a weak base, it is the same strategy with a couple of extra steps. Let’s see how it works with an example of a weak base ammonia (NH 3). Example: Calculate the pH of a 1.5 M solution of ammonia. K b = 1.8 x 10-5. The first step is to write the reaction of the weak base water! Remember, the water in this case acts as an acid ...

WebMay 14, 2015 · 12K views 7 years ago Weak acids dissociate partially in solution to release H+, and the concentration of H+ is much lower than concentration of the weak acid. Similiary, weak bases... WebSimilarly, you will then titration a weak base (NH 3) with a strong acid to calculate the value of K b (base dissociation constant) for the weak base. Finally, you will use the pH meter in order to determine the effect of dissolved salts on the pH of water through the process of hydrolysis and the effect of adding an acid or base to a buffer. kh ba08 バッテリー
