Assertion and Reasoning
Assertion: The aqueous solutions of glucose and alcohol do not show acidic character.
Reason: Aqueous solutions of glucose and alcohol do not give H+ ions.
Explanation
Acids are substances that donate H+ ions (protons) when dissolved in water. In contrast, bases are substances that accept H+ ions or donate OH- ions when dissolved in water. The acidity or basicity of a substance is measured on the pH scale, which ranges from 0 to 14. A pH of 7 is considered neutral, while pH values less than 7 are acidic and pH values greater than 7 are basic.
Glucose and alcohol are organic compounds that do not contain any acidic functional groups such as carboxylic acid (-COOH) or sulfonic acid (-SO3H). Therefore, they cannot donate H+ ions and do not show acidic character in aqueous solutions.
The assertion is true because aqueous solutions of glucose and alcohol have a pH close to 7, which is neutral.
The reason is also true because the presence of H+ ions is necessary for a substance to be acidic, and glucose and alcohol do not give H+ ions in water.
Therefore, both assertion and reason are true, and the reason correctly explains the assertion.
Conclusion
The correct answer is option A: Both assertion (A) and reason (R) are true, and reason (R) is the correct explanation of assertion (A).
