WebSulfuric acid also prevents manganese from oxidising to manganese dioxide. We cannot carry out the titration in the presence of acids such as hydrochloric acid or nitric acid. Hydrochloric acid is an oxidising agent that reacts with manganate(VII) to form chlorine. As with the previous titration, permanganate acts as a self indicator. WebIn a strong acid-strong base titration, the acid and base will react to form a neutral solution. At the equivalence point of the reaction, hydronium (H+) and hydroxide (OH-) ions will …
