Step 1
Who originally stated this theory of acids?
Answer
The theory of acids presented in the student's report corresponds to the Arrhenius definition, which specifies that acids are substances that produce hydrogen ions (H⁺) when dissolved in water. This concept was introduced by Svante Arrhenius in the late 19th century. Therefore, the correct answer is:
