WebSep 22, 2024 · The main difference between a strong base and a weak base is that strong bases can completely dissociate to give all available hydroxyl ions to the system whereas … WebNov 4, 2024 · A strong acid like HCl donates its proton so readily that there is essentially no tendency for the conjugate base Cl – to reaccept a proton. Consequently, Cl – is a very weak base. A strong base like the H – ion accepts a proton and holds it so firmly that there is no tendency for the conjugate acid H 2 to donate a proton.
WebFeb 2, 2024 · Weak bases react with water to produce the hydroxide ion, as shown in the following general equation, where B is the parent base and BH+ is its conjugate acid: B(aq) + H 2O(l) − ⇀ ↽ − BH + (aq) + OH − (aq) The equilibrium constant for this reaction is the base ionization constant ( Kb ), also called the base dissociation constant: WebDec 30, 2024 · The best way to tell or determine whether acid or base is strong or weak to look at following condition-Any acid that dissociates 100% into ions is called a strong …
WebAug 9, 2024 · In a strong acid-strong base titration, the equivalence point is reached when the moles of acid and base are equal and the pH is 7. In a weak acid-strong base titration, the pH is greater than 7 at the equivalence point. In a strong acid-weak base titration, the pH is less than 7 at the equivalence point.
