Bases yield solutions in which the hydrogen ion activity is lower than it is in pure water, i.e., the solution is said to have a pH greater than 7.0 at standard conditions, potentially as high as 14 (and even greater than 14 for some bases). The formula for pH is: Bases are proton acceptors; a base will receive a hydrogen ion from water, H2O, and the remaining H concentration in the solution determines pH. A weak base will have a higher H conc… Web6 apr. 2024 · Weak bases can be defined as substances that do not dissociate completely into their constituent ions when dissolved in water solution.

Identifying weak bases and strong bases - Khan Academy
WebFinding the pH of a weak base is similar to finding the pH of a weak acid. However, there are a few differences. Let’s look at an example together. A 0.15 mol dm-3 solution of NH … WebBases are proton acceptors; a base will receive a hydrogen ion from water, H 2 O, and the remaining H + concentration in the solution determines pH. A weak base will have a higher H + concentration than a stronger base because it is less completely protonated than a stronger base and, therefore, more hydrogen ions remain in its solution.
