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… Web28 mrt. 2024 · Main Differences Between Strong Base and Weak Base. Strong bases ionize completely during a reaction with acid, whereas weak bases show incomplete …
