For example, if 0.6 moles of HNO 3are dissolved in a liter of water, you would say [HNO 3] = 0.6 M. A. Because HNO 3 is a strong acid, it dissociates almost completely in water.
WebApr 5, 2015 · For a conjugate acid-base pair, in water, it is Ka . Kb = Kw = 10*-14 (25 ºC). So, the rule is "the stronger the acid, the weaker the conjugate base and vice-versa", which is …
WebA weak acid has a pK a value in the approximate range of -2 to 12 in water. Acids with a pK a value of less than about -2 are said to be strong acids. A strong acid is almost completely dissociated in aqueous solution; it is dissociated to the extent that the concentration of the undissociated acid becomes undetectable.
WebJun 18, 2024 · Many acids and bases are weak; that is, they do not ionize fully in aqueous solution.
