Acidic conditions are characterized by an excess of which ion?

• A. OH- ions
• B. Na+ ions
• C. H+ ions
• D. Cl- ions

Answer: (C)

In an acidic solution, the characteristic feature is the presence of an excess of hydrogen ions, represented as H+. Acids are defined by their ability to donate protons (H+) in a chemical reaction, which results in a higher concentration of these ions compared to hydroxide ions (OH-). This imbalance between H+ and OH- ions determines the acidity of the solution; when H+ ions outnumber OH- ions, the solution is acidic. In practical applications, understanding the behavior of H+ ions is critical in various fields, including chemistry, environmental science, and even in cathodic protection systems, where pH levels can influence corrosion processes. An excess of H+ contributes to lower pH values, indicating stronger acidity, which can affect material integrity and the efficacy of cathodic protection methods.
