CHEMICAL PROPERTIES OF ACIDS: 1. React with reactive metals (above H in Reactivity Series) to form Salt & Hydrogen Gas 2. React with Metal Carbonates to form Salt, Carbon Dioxide & Water.3. React with Bases/Alkali to form Salt & Water (Neutralistion Reaction).HEMICAL PROPERTIES OF ACIDS: 1. React with reactive metals (above H in Reactivity Series) to form Salt & Hydrogen Gas 2.

An element/compound having a sour taste is a chemical property because it is an evidence that it is an acid. Being an acid tells us that it will react to a base when combined. The last option is also a chemical property because it tells that it reacts with an acid to form H2 gas. The chemical property of element/compound distinguishes it to another. Density and luster is a physical property because its value depends physically. A decrease in mass will result to a change in density.
