Below are some ideas and generalizations to keep in mind that will help in recognizing types of species . acidic NH4CN is acidic, basic or neutral? For the next three problems, consider 1.0 L of a solution which is 0.55 M HF and 0.2 M NaF (Ka for HF = 7.2 x 10-4). Normally, an amino acid produces a nearly neutral solution since the acid group and the basic amine group on the root amino acid neutralize each other in the zwitterion. Acid-base reactions are called neutralization reactions because the reaction of an acid with a base generally produces a salt with little or no acid-base character and, in many cases, water. Home. Calibo Skittles Edibles, For those that are not neutral, write a balanced chemical equation for the reactions causing the solution to be acidic or basic. CH3NH3CN basic, acidic, or neutral? It only takes a minute to sign up. C6H5NH3+, conjugate base is a weak base, therefore it is potentially acidic NO2-, conjugate acid is a weak acid, therefore the salt is also potentially basic However, since the Ka > Kb, the solution must be acidic So it has both nature acidic on basic in its constituent, it will act as a neutral soul.
