How does temperature affect the solubility of sodium chloride?
Solubility increases with temperature.
What are these factors that affect solubility?
Three factors that affect solubility are temperature, pressure, and the particular properties of the solvent and solute.
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.
What is lattice energy of Crcl3?
5396kJ/mol
Energy released when a salt is formed from a gasious ions?
lattice energy.
What factors affect lattice energy?
Ionic Charge and Ionic Radius - the smaller the radius the greater the lattice energy
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 the lattice energy of rubidium iodide because lattice energy is inversely proportional to atomic radius.
How does temperature affect solubility of a substance which involves endothermic process in forming a solution?
endothermic substances absorb energy when dissolved. Therefore supplying energy(heat) externally will increase the solubility.
Why is sodium nitrate more soluble than potassium nitrate?
Yes. Because hydration energy of Na+ is greater than K+. More the hydration energy greater is solubility. A compound is soluble if hydration energy is greater than lattice energy.
What is the lattice energy of a compound?
Ions release some amount of energy when they get together to form a lattice. If it is needed to be seperated into ions again, the same energy should be absorbed. The energy to break 1 mole of a lattice at the standard temperature and pressure is defined as the standard lattice energy. Using formulae, the lattice energy at any conditions can be found as the standard values are tabulated.
How does changes to the diamond lattice affect the diamond?
Once formed, the diamond lattice does not change. Irregularities in the lattice, however, may affect the stone's colour.
Electrostatic attraction between ions causes the release of what?
it releases lattice energy
Can pressure affect solubility of a substance in a solution?
Pressure can affect the solubility but the effect is not important.
How does an impurity affect the solubility of substance?
It will decrease the solubility of substance
What are factors affecting lattice energy?
Ionic Charge and Ionic Radius - the smaller the radius the greater the lattice energy
How does pressure affect the solubility of gases?
At high pressure the solubility increase.
How does temperature affect the solubility of sodium chloride?
Solubility increases with temperature.
