The true statement regarding acids is that they react strongly with metals. This characteristic is a defining property of many acids, particularly strong acids like hydrochloric acid or sulfuric acid. When acids come into contact with certain metals, a chemical reaction occurs that often produces hydrogen gas and a salt. This reaction is why acids can be both corrosive and reactive with various metal materials.

The other properties listed do not accurately apply to acids. For instance, acids typically have a sour taste, not a bitter one, and they do not feel slippery; those characteristics are usually associated with bases. Additionally, acids generally have a low pH value, typically ranging from 0 to 7, in contrast to the high pH values associated with bases.
