water ionization

The ionization energies of the elements of oxygen family are less than those of nitrogen family. As we move down the group from oxygen to polonium, the ionization energy decreases. Explanation: We expect that the ionization energy of oxygen should be more than that of..

Pure water being a weak electrolyte under goes self ionization to a small extent as follows: The equilibrium constant for this reaction is: ..

3 O + and OH - are equal and so we can write, [H 3 O + ] = [OH - ] If, K w = [H 3 O + ] [OH - ] = 1.008 x 10 -14 mol 2 L -2 then, [H 3 O + ] [OH - ] = 1.008 x 10 -14 [H 3 O + ] ..

Certain covalent molecules i.e. those molecules that share a pair of electrons, one being provided by each atom, also undergo ionization when dissolved in water. As a matter of fact the hydrogen ion when mixed with water combines with a molecule of water to f..

The ionization constant (K) is then given b..

The amount of energy required to remove the most loosely bound electron from an isolated gaseous atom is called ionization energy (IE..

The equilibrium concentration of various species at equilibrium can be represented in terms of degree of ionization as: Then according to law of mass action, ..

Ionization energy of hydrogen is very high in comparison to alkali metals. For example, IE of H = 1312 kJ mol - 1 , IE of Li = 520 kJ mol - ..

Alkali metals have the lowest ionization energy in each period. Within the group, as we go down, the ionization energies of alkali metals decrease due to their atomic size being the largest in their respective periods. In large atoms the valence electrons are loosely held by t..

. By supplying enough energy, it is possible to remove an electron from an atom. The element is first brought into the vapour state. Then the electron is removed by supplying energy equivalent to the ionization potential. In referring to the Periodic table of ionisation potentials (in ele..
