Weak base definitions

weak base

Compare with strong base. A base that only partially dissociates into ions in solution. Weak bases are weak electrolytes. Ammonia is an example of a weak base; the reaction NH3_{(aq) + H}2_{O(l) = NH}4_⁺(aq) + OH^-(aq) is reversible.

Weak base

After acquiring pOH from the previous pOH formula, pH can be calculated using the formula pH = pKw - pOH where pKw = 14.00. ==Percentage protonated== As seen above, the strength of a base depends primarily on pH. To help describe the strengths of weak bases, it is helpful to know the percentage protonated-the percentage of base molecules that have...
