What does acid mean in science
An acid is a chemical that gives off protons or hydrogen ions and/or takes up electrons. Most acids contain a bonded hydrogen atom that can dissolve (dissociate) to form a cation and an anion in water. The higher the concentration of hydrogen ions produced by an acid, the higher the acidity and the lower the pH of the solution.
