Because the nitrogen atom consists of one lone pair which can be used to And so I go over here and put "X", and then for hydroxide, X over here, alright? an equilibrium expression. is a conjugate acid-base pair, and the Ka value for acetic acid is easily found in most text books, and the Ka value is equal to 1.8 x 10-5. Explain. pH Calculator | How To Calculate pH? the concentration is X. Explain. The reaction of the weak base aniline, C6H5NH2, with the strong acid hydrochloric acid yields aniline hydrochloride, C6H5NH3Cl. However, they must first be provided by dissolving an appropriate solid salt compound in liquid water. Well, we're trying to find the And we're starting with .25 molar concentration of sodium acetate. Note that there is no $\ce {OH-}$ to start with (very little in reality), so equation $ (1)$ is not applicable. How can a base be used to neutralize an acid? X represents the concentration Is a solution with OH- = 4.8 x 10-3 M acidic, basic, or neutral? Benzoic acid (C 6 H 5 COOH) and aniline (C 6 H 5 NH 2) are both . worry about X right here, but it's an extremely small number, .050 - X is pretty much the same as .050 So we plug this in and The total number of stars for this article is: C6H5NH2 + HCl = C6H5NH3Cl | Chemical Equation. The base which a certain acid turns into.Every acid had a conjugate base:HX (acid) X- (conjugate base)The acid is also called the base's conjugate acid.
