This mixture boils at 338 0 C and has a density of 1. A great deal of heat is released when concentrated sulfuric acid and water are mixed;therefore, acid should always be added to water with sufficient stirring to prevent splattering and boiling. Hydrochloric acid undergoes 100% ionization so it is called a strong acid. You know only one value of boiling point for your substance. Allyl chloride may polymerize violently under conditions involving an acid catalyst, such as sulfuric acid [Ventrone 1971].
