Webstrong bases. Examples: NaOCH3 (any NaOR), LiCH3 (any RLi), NaOH or KOH, NaCN or KCN, NaCCR (acetylide anion), NaNH2, NaNHR, NaNR2 Weak Bases – • Typically … 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…
