WebRule of thumb is: Weak acids have strong conjugate bases, while weak bases have strong conjugate acids. As shown in the above two reactions, if HA is a weak acid, then its conjugate base A - ^\text{-} - start superscript, start text, negative, end text, end superscript will … WebA weak base is any base that reacts with water (accepts H + ions) to a very small extent, usually less than 5 - 10%. An aqueous solution of a weak base in a state of equilibrium would consist mainly of the unionized form of the base, and only a small amount of hydroxide ions and of the cation (conjugate acid) of the weak base.
WebOct 29, 2024 · NH3 is a weak base; however, its pH is 11 and acts as an amphoteric species. Amphoteric species is the species that behave as an acid and the base. Its basicity value (pk b) is 4.75, and it is miscible soluble in water. Three concepts of acid and bases will explain Ammonia’s acidic or basic nature. 1. WebMar 20, 2024 · Weak-base resins as a rule do not remove weak acids such as carbonic or silicic but will neutralize strong acids (nitric, sulfuric and hydrochloric). Certain weak-base resins (acrylic) can also reduce carbonic acid. Resin capacity, therefore, has to be defined in terms of strong-acid/weak-acid and strong-base/weak-base functions. ...
