Chapter 22, Problem 10STP

Interpretation Introduction

Interpretation:

The type of compound that accepts hydrogen ion needs to be determined.

Concept introduction:

According to Arrhenius theory, an acid and a base is explained on the basis of removal of hydrogen and hydroxide ions respectively in an aqueous solution. Bronsted-Lowry acid and base is explained with the help of protons involvements.

Answer to Problem 10STP

Correct Answer: Option (d) is correct.

Explanation of Solution

Reason for correct options:

According to Arrhenius theory, acid donates hydrogen ions in the aqueous solution and base donates hydroxide ions in the aqueous solution.

According to Bronsted-Lowry theory, acids are species which donates hydrogen ions and bases are species which accept hydrogen ions. Thus, a Bronsted-Lowey base accepts ${\mathrm{H}}^{+}$ ions. The correct option is (d).

Conclusion

Reason for incorrect options:

An Arrhenius acid donates hydrogen ion in the aqueous solution, an Arrhenius base donates hydroxide ion in the aqueous solution and a Bronsted-Lowry acid donates ${\mathrm{H}}^{+}$ ions. Therefore, options (a), (b) and (c) are incorrect options.
