Answer the following question given this paragraph: The strength of an acid depends on the concentration of hydrogen ions it produces when dissolved in water. A stronger acid produces a greater concentration of ions than a weaker acid. For example, when hydrogen chloride is added to water, all of it breaks down into H + and Cl - ions. Therefore, it is a strong acid. On the other hand, only about 1 percent of acetic acid breaks down into ions, so it is a weak acid. Q: The strength of what depends on the concentration of hydrogen ions it produces when dissolved in water? Choices: - the solution - electricity - the base - acid A:
(Answer)
acid
