WebbWhat is the pH of aniline? 7.818 Hence, the pH of the solution is 7.818. The ionization constant of the conjugate acid of aniline is calculated by dividing the ionic product of water by the ionization constant of aniline. Read More: How does PCM work? What are aniline derivatives? Term. aniline derivatives. WebbN,N-Dimethylaniline ( DMA) is an organic chemical compound, a substituted derivative of aniline. It consists of a tertiary amine, featuring dimethylamino group attached to a phenyl group. This oily liquid is colourless when pure, but commercial samples are often yellow. It is an important precursor to dyes such as crystal violet .
WebbThe pH of an aqueous solution is based on the pH scale which typically ranges from 0 to 14 in water (although as discussed below this is not an a formal rule). A pH of 7 is considered to be neutral. A pH of less than 7 is considered acidic. A pH of greater than 7 is then considered basic. Webb1 apr. 2024 · Now, the pH of the solution is equal to the negative logarithm of the concentration of the hydrogen ions. p H = − log [ H +] = − log 1.52 x 1 0 − 8 = 7.818 …

WebbThe effect of this is that the pH of a solution of phenylamine will be quite a bit lower than a solution of ammonia or one of the aliphatic amines of the same concentration. For example, a 0.1 M phenylamine solution has a pH of about 9 compared to a pH of about 11 for 0.1 M ammonia solution. Why is phenylamine such a weak base?
