Lattice energy is greater than hydration energy when the overall energy released during the formation of the crystal lattice (lattice energy) is higher than the energy absorbed during the separation of ions from the lattice by water molecules (hydration energy). This typically occurs for highly charged ions that form strong ionic bonds and have a high charge-to-size ratio.

Is iron carbonate a soluble salt?
Its Lattice energy is greater than the solvation energy of water.
What is hydration energy?
Hydration Energy is involved in the solution process. The solution process involves three steps all including a change in enthalpy. The first delta H (change in enthalpy) is the process by which water molecules overcome attractive forces in the solute particles to break chemical bonds. This process is endothermic. The second step delta H 2 is the separation of solvent molecules to accommodate the solute. This step also requires energy and is endothermic (delta H is greater than 0) The final step is the formation of new attractive interactions between solute and solvent particles and is exothermic (delta H is less than 0). The sum of delta H 1, 2, and 3 is the overall enthalpy of the solution process and this sum is known as the hydration energy. If the sum of delta H 1 and 2 is greater in magnitude than the delta H 3 (which is a negative number) the overall process will be endothermic. If the sum of delta H 1 and 2 is lesser in magnitude than delta H 3 the overall process will be exothermic.
Does a crystal lattice have lower potential energy than a neutral atom?
Yes, in a crystal lattice, atoms are arranged in a repeating pattern that minimizes their potential energy. This arrangement is more stable and has lower potential energy compared to individual neutral atoms.
How large would the lattice energy need to be for the formation of NaCl2 to be exothermic?
The lattice energy needed for the formation of NaCl2 to be exothermic would need to be larger than the energy required to break the bonds in Na and Cl2 and smaller than the energy released when the new Na-Cl bonds are formed in NaCl2. This would result in a negative overall enthalpy change for the reaction, indicating an exothermic process.
Why does Ca have a higher ionization energy than Ga?
because it lower than Ba as you go down ionization energy increases
What can you say about the relative magnitudes of the lattice energy of lithium iodide and its heat of hydration?
The lattice energy of lithium iodide is typically larger than its heat of hydration. This means that more energy is required to break the ionic bonds in the solid lattice of lithium iodide than is released when the ions are hydrated in solution.
What can you say about the relative magnitudes of the lattice energy of ammonium chloride and its heat of hydration?
The lattice energy of ammonium chloride is typically greater than its heat of hydration due to the strong electrostatic attractions between the positively charged ammonium ions and negatively charged chloride ions in the crystal lattice. While the heat of hydration refers to the energy released when water molecules surround and interact with the individual ions in solution.
Why is sodium nitrate more soluble than potassium nitrate?
Sodium nitrate is more soluble in water than potassium nitrate because sodium ions have a smaller size and higher charge density compared to potassium ions, which helps sodium nitrate molecules dissociate more easily in water. This results in more sodium nitrate ions being able to interact with water molecules and increase its solubility.
Can ionic compounds dessolve in water?
Ionic compounds can only be dissolved in water if the energy of hydration is greater than latice energy of that compound
Is NaCl has greater lattice energy than MgO?
because Mg and O have more electropositivity and electronegativity rspt. than Na and Cl atoms.
Why does the melting point of group 2 oxides decrease down the group?
Group Two elements form oxide consisting of ionic bonds. With that in mind, as you go down group two, the ionic radius increases due to an addtion of a electron shell, so therefore, melting point of group2 oxide decreases down group because the distance between the O2- and Group two ion are further apart. The increase of bond length results in less energy needed to break the ionic bonds, resulting in decrease of energy.
Why lattice energy of nacl is greater then kcl and kbr?
Lattice energy increases with greater charge and smaller size. Since the charges are the same for both compounds, you have to look at the sizes of the atoms, K and Na, and since both have Cl, you don't have to compare that with anything. K is larger than Na, so since NaCl has a smaller size and the same charge, it has higher lattice energy.
Is iron carbonate a soluble salt?
Its Lattice energy is greater than the solvation energy of water.
Why is the lattice energy of potassium bromide more exothermic than the lattice energy of rubidium iodide?
The lattice energy of potassium bromide is more exothermic than that of rubidium iodide because potassium and bromine have smaller atomic sizes and higher charges, which leads to stronger ionic bonding in potassium bromide. Rubidium and iodine have larger atomic sizes and lower charges, resulting in weaker ionic bonding in rubidium iodide. The stronger ionic bonding in potassium bromide requires more energy to break, resulting in a more exothermic lattice energy.
Why is lattice energy of MgF2 greater than MgCl2?
since ca2+ has a larger atomic radii compared to Mg2+ (and the same for F and CL2), the electrons are dispersed over a wider surface area and so have a lesser strength than that of magnesium. Hence, with a smaller atomic radii, Magnesium has stronger attractive forces with require more energy to be broken and therefore making it more exothermic than calcium.
Does calcium oxide have a higher lattice energy than magnesium oxide?
Yes, calcium oxide has a higher lattice energy than magnesium oxide. This is due to the higher charge of the calcium ion compared to the magnesium ion, leading to stronger electrostatic attraction between the ions in the lattice structure.
Which has higher lattice energy AgCl and AgBr?
AgCl has a higher lattice energy than AgBr because Cl- is a smaller ion than Br-, resulting in stronger electrostatic interactions in AgCl.
