The adjective ACIDIC has 2 senses: 1. being or containing an acid; of a solution having an excess of hydrogen atoms (having a pH of less than 7). 2. being sour to the taste. Familiarity information: ACIDIC used as an adjective is rare.Dictionary entry details.eing or containing an acid; of a solution having an excess of hydrogen atoms (having a pH of less than 7).
An acid is a substance that donates hydrogen ions. Because of this, when an acid is dissolved in water, the balance between hydrogen ions and hydroxide ions is shifted. Now there are more hydrogen ions than hydroxide ions in the solution.This kind of solution is acidic.o be more precise, pH is the negative logarithm of the hydrogen ion concentration: pH = âlog [H+]. The square brackets around the H + automatically mean concentration to a chemist. What the equation means is just what we said before: for each 1-unit change in pH, the hydrogen ion concentration changes ten-fold.
