WebJun 7, 2015 · A polyethylene or polypropylene plastic is composed of long lengths of C-C chains, which have no bonds susceptible to the acid. The C-C chain is inert to both dilute and conc. acid. Hydrochloric, nitric, and sulfuric acids are now routinely supplied in plastic rather than glass bottles. Hydrofluoric acid, which would etch glass, has always been ... WebFor the weak acid + strong base, the pH is above 7 at the equivalence point. If there is strong acid or strong base left over after the equivalence point, this can be used to find the pH of the solution. Next, let's take a look at sulfuric acid. This unique polyprotic acid is the only one to be completely deprotonated after the first step:
