WebMar 18, 2024 · Acids are chemical compounds that release hydrogen ions (H+) when placed in water. For example, when hydrogen chloride is placed in water, it releases its hydrogen ions and the solution becomes hydrochloric acid. Bases are chemical compounds that attract hydrogen atoms when they are placed in water. An example of a base is … WebChemical Properties of Bases. In the chemical properties of acids and bases, we now focus on bases. Bases change the colour of litmus from red to blue. They are bitter in taste. Bases lose their basicity when mixed with acids. Bases react with acids to form salt and water. This process is called Neutralisation Reaction (Read).
