Strong acids always have a very low ph
WebLower pH number means stronger acid, higher pH number means stronger base. It can be a little confusing, but the lower the pH of a substance is, the stronger of an acid it is. Sometimes it is more helpful to think that the further away from neutral a substance is, the stronger it is in either the acidic or basic direction. http://chemed.chem.purdue.edu/genchem/topicreview/bp/ch11/conjugat.php
