Question

Which of the following statements correctly distinguishes between an acidic and a basic solution? . A. An acidic solution contains a high ratio of hydrogen ions to hydroxide ions and a basic solution contains a ratio that is closer to one.. B. An acidic solution has a high pH and a basic solution has a low pH.. C. An acidic solution has only hydrogen ions and a basic solution has only hydroxide ions. D. An acidic solution has a much higher hydrogen ion concentration than a basic solution.

Answer 1

Acids are ionic compounds that break apart in water to form a hydrogen ion. The strength of an acid is based on the concentration of hydrogen ions in a solution. The more hydrogen ions, the stronger the acid. Bases are ionic compounds that break apart in water to form negatively charged hydroxide ions. The strength of the base is based on the concentration of hydroxide ions. 
Hence, letter C is the correct answer.
