WebThe pH scale is used to classify substances as acids and bases. The scale goes from 0 to 14. Things that are acids have a pH number that is less than 7. The lower the number, the stronger the acid. Bases have pH values higher than 7. The higher the number, the stronger the base. An example of a strong base is drain cleaner or oven cleaner. WebAcids provide the H + ion; bases provide the OH - ion; and these ions combine to form water. H + ( aq) + OH - ( aq ) H 2 O ( l) The Arrhenius theory has several disadvantages. It can be applied only to reactions that occur in water because it defines acids and bases in terms of what happens when compounds dissolve in water. WebStrong acids are corrosive and strong bases are caustic; both can cause severe skin damage that feels like a burn. However, mild acids and bases are common and relatively harmless to us.
