A beaker of concentrated hydrochloric acid has a pH of 1. What colour will full range universal indicator turn if it is added to this beaker? Is it a strong or a weak acid?


Hydrochloric acid with a pH value of 1 will impart a red colour when treated with a universal indicator. The pH value is 1 and as the pH decreases from 7 the solution becomes more acidic and the hydrogen ion concentration increases. Therefore, it will be a strong acid.
