One would expect proton to have very largea)Chargeb)Ionization potentialc)Hydration energyd)Radius. [1993]Correct answer is option 'C'. Can you explain this answer?

Question

Answer

Hydration energy is inversely proportional to ionic size. This is because smaller the ionic size greater is the effective nuclear charge and greater will be it's tendency to attract the 'O' atom of water towards itself to get itself hydrated. More hydration leads to a greater release of energy i.e hydration energy.

Answer

Ionization potential can also be the answer. A proton is
a atom which has a positive charge. So due to the positive charge it's atomic size decrease which in turn increases the I. P

Answer

Proton is very small in size but it have very large hydration energy.

Answer

Introduction

When comparing the properties of protons, one would expect them to have a very large hydration energy. This is due to the nature of protons and their interaction with water molecules. In order to understand why this is the case, it is important to consider the characteristics of protons and the concept of hydration energy.

Protons and their properties

- Protons are subatomic particles that carry a positive charge and are found within the nucleus of an atom.
- They have a mass of approximately 1 atomic mass unit (AMU) and a charge of +1.
- Protons play a crucial role in determining the chemical and physical properties of an element.

Hydration energy

- Hydration energy refers to the energy released when a solute particle is surrounded by water molecules and forms a hydrated ion.
- It is a measure of the strength of the interaction between the solute particle and water molecules.
- The stronger the interaction, the higher the hydration energy.

Explanation of the correct answer - option 'C'

Hydration energy is the correct answer for several reasons:

1. Electrostatic attraction
- Protons have a positive charge, while water molecules have a partial negative charge on their oxygen atom.
- This leads to an electrostatic attraction between the proton and the oxygen atom of the water molecule.
- The strong electrostatic attraction results in a significant release of energy, contributing to a large hydration energy.

2. Formation of hydronium ion
- When a proton is dissolved in water, it combines with a water molecule to form a hydronium ion (H3O+).
- This process involves the transfer of a proton from the solute particle to the water molecule.
- The formation of the hydronium ion is highly exothermic, releasing a large amount of energy.

3. High dielectric constant of water
- Water has a high dielectric constant, which means it can effectively shield the electrostatic interactions between charged particles.
- This allows water molecules to stabilize and solvate the proton, resulting in a large release of energy.

Conclusion

In summary, protons have a very large hydration energy due to the strong electrostatic attraction between the positive charge of the proton and the partial negative charge of the oxygen atom in water molecules. Additionally, the formation of the hydronium ion and the high dielectric constant of water contribute to the large hydration energy exhibited by protons.
