Which alkaline earth metal has the highest hydration enthalpy?

– Therefore Beryllium sulphate has high hydration and less lattice energy among the given options. So, the correct answer is “Option B”.

What is hydration enthalpy of alkaline earth metals?

The energy released as a result of the formation of new bonds between ions and water molecules is called hydration enthalpy. Hydration enthalpiesof alkaline earth metal ions decrease with the increasing ionic size down the group.

What is the order of hydration enthalpy of alkali metal ions?

Na+>Li+>K+>Cs+>Rb+

Which alkali metal has least hydration enthalpy?

Lithium ion
“Lithium ion has the smallest hydration enthalpy of all the alkali metals.” Answer.

Which of the following alkaline earth metal is strongest reducing agent?

Barium
Barium being the largest non-radioactive atom in the group with the lowest ionization energy easily loses its electrons and is therefore the strongest reducing alkaline earth metal.

Why do alkaline earth metals form 2+ ions?

All the alkaline earth metals have two electrons in their valence shell, so they lose two electrons to form cations with a 2+ charge. In chemical terms, all of the alkaline metals react with the halogens to form ionic alkaline earth metal halides.

Why hydration enthalpy of lithium is highest?

Lithium exerts the greatest polarizing effect out of all the alkali metals on the negative ion. Being smallest in alkali metals, it’s ion Li+ is smaller, this increases the charge density for this job appreciably. Consequently, its hydration energy becomes large.

Which alkali metal salts are mostly hydrated?

Why is lithium salts mostly hydrated. Lithium is known to have the smallest size among all alkali metals. This is the primary reason why the Li+ ion has the ability to polarize water molecules more easily when compared to other alkali metals.

Which has highest hydration enthalpy?

The lithium-ion has by far the highest hydration enthalpy in Group 1 and the small fluoride ion has by far the highest hydration enthalpy in Group 7. Lithium exerts the greatest polarizing effect out of all the alkali metals on the negative ion.

Which element has lowest hydration energy?

“Lithium ion has the smallest hydration enthalpy of all the alkali metals.”

Which reducing agent is strongest?

Na
The elements which readily lose the electron act as a strong reducing agent. Na is the strongest reducing agent, while Cl- is the weakest reducing agent.

Which metal is strongest reducing agent?

lithium
The best reducing metal is lithium, with the maximum negative value of electrode potential. By convention, reduction potential, or the propensity to be diminished, are the normal electrode potentials.

What are the hydration enthalpies of alkaline earth metal?

Hydration enthalpiesof alkaline earth metal ions decrease with the increasing ionic size down the group. Hydration enthalpies of alkaline earthmetal ions are larger than those of alkali metal MgCl 2 and CaCl 2 exist as hydrates in the form of MgCl 2 .6H 2 O and CaCl 2 6H 2 O.

Why are alkaline metals more extensively hydrated than alkali metals?

Reason: Due to smaller size of alkaline earth metal ions as compared to alkali metal ions ,the hydration enthalpies of alkaline earth metal ions are larger than those of alkali metal ions. The compounds of alkaline earth metals are more extensively hydrated than those of alkali metals.

Which is the correct order of hydration enthalpies?

The correct order of hydration enthalpies of alkali metal ions is – askedMay 13, 2019in Chemistryby Ruksar(68.7kpoints) jee mains 2019 0votes 1answer Compared the 2nd Ionisation enthalpies and Hydration enthalpies of Alkali and Alkaline earth metals/ions.

Why do alkaline earthmetal ions decrease in size?

The energy released as a result of the formation of new bonds between ions and water molecules is called hydration enthalpy. Hydration enthalpiesof alkaline earth metal ions decrease with the increasing ionic size down the group. Hydration enthalpies of alkaline earthmetal ions are larger than those of alkali metal
