Write the acid-base reaction between the weak base ammonia NH3 and the strong acid hydrochloric acid HCl. • Be sure to include the charges on any ions in the equation. If the charge is +1 or -1, only include the + or the - superscript, not the number 1. • Do NOT include state phases in ...
Answer to Ammonia (NH3) is a weak base with a pkb of 4.75. a) We have ,pKb = - log K b Therefore, K b = 10 - pKb = 10 - 4.75 = 1.778 x 10 -05 Consider dissociation of ammonia in water as NH3 + H2O NH4+ + OH - For above reaction , K b = [NH4+ ] [OH - ] / [NH3 ] If X moles of ammonia dissociated at equilib. …
