HCL and HNO3 show acidic character in aqueous solutions while alcohol and glucose solutions do not. Give reasons?

Question

Answer

Hcl and hno3 show acidic character in aqueous solutions cause they ionize in aqueous solution to form ions ,while compounds like glucose and alcohol do not .Hence they do not show acidic character.

Answer

HCL and HNO3  shows acidic character in aqueous solution while alcohol and glucose solutions do not because they realise  H + ions in aqueous solutions and alcohol and glucose do not release it in aqueous solution  .....

Answer

Acidic Character of HCL and HNO3 in Aqueous Solutions

HCL (hydrochloric acid) and HNO3 (nitric acid) are both strong acids that dissociate almost completely in aqueous solutions. This means that they release hydrogen ions (H+) when dissolved in water, resulting in an increase in the concentration of H+ ions in the solution. As a result, the solution becomes acidic.

1. Ionization of HCL and HNO3
- HCL dissociates into H+ and Cl- ions: HCL → H+ + Cl-
- HNO3 dissociates into H+ and NO3- ions: HNO3 → H+ + NO3-

The release of H+ ions in the solution is responsible for the acidic character of HCL and HNO3. These hydrogen ions can easily react with water molecules to form hydronium ions (H3O+), further increasing the acidity of the solution.

2. Acid-Base Reactions
HCL and HNO3 can also participate in acid-base reactions with other substances. In aqueous solutions, they can donate H+ ions to react with species that can accept them, such as hydroxide ions (OH-) or basic compounds. This further supports their acidic character.

Alcohol and Glucose Solutions

Unlike HCL and HNO3, alcohol and glucose solutions do not show acidic character. This is because they do not release H+ ions in significant amounts when dissolved in water.

1. Alcohol
Alcohols are organic compounds that contain an -OH (hydroxyl) functional group. Although the -OH group can donate a proton (H+) to form an H3O+ ion, the reaction is not as favorable as in the case of strong acids like HCL and HNO3. Therefore, alcohols do not readily dissociate into H+ ions and do not significantly increase the concentration of H+ ions in the solution.

2. Glucose
Glucose is a simple sugar and is not an acid. It does not contain any acidic functional groups that can release H+ ions. In fact, glucose is classified as a neutral compound.

Conclusion
HCL and HNO3 exhibit acidic character in aqueous solutions due to their ability to release H+ ions. On the other hand, alcohol and glucose solutions do not show acidic character because they do not release H+ ions in significant amounts.
