Document Summary
Section 12. 4 the hydrogen atom and hydrogen ion. In order to better understand what an acid is we must first look at the hydrogen atom and hydrogen ion: the hydrogen atom: Has a single proton, which is positively charged, and a single electron, which is negatively charged. The result is an electrically neutral element: a hydrogen ion (h+): charged proton. It"s a hydrogen atom that has lost its electron, leaving only the positively. In some situations, the hydrogen ion may simply be called a proton. Section 12. 5 what are acids and bases: an acid: It"s any molecule that will release hydrogen ions when put in a solution. For example, hydrochloric acid (hcl) will break apart (or dissociate) into free hydrogen ions (free h+) and chloride ions (cl ) as shown at right: it is the presence of the free h+ that makes a solution acidic. The more free h+, the more acidic the solution, and visa versa.
