The formula that represents an acid is B) HCl.
HCl stands for hydrogen chloride. When hydrogen chloride is dissolved in water, it forms hydrochloric acid, which is a strong acid. The presence of hydrogen (H) at the beginning of a formula is a common indicator that the compound can form an acid when dissolved in water. This is because acids are characterized by their ability to donate a proton (H+) in an aqueous solution, which HCl can do.
