ionization of hno2 in water

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..

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 + ] ..

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

The ionization energy of hydrogen is quite close to that of halogens. H : 1312 kJ mol - 1 , Cl : 1255 kJ mol - ..

Due to a fairly large size of the atoms, alkaline Earth metals have low ionization energies when compared to 'p' block elements. Down the group the ionization energy decreases as atomic size increases. This is due to new shells being added and increase in the magnitude of the s..

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, ..

. 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..

The ionization energies of halogens are very high. This indicates that they have very little tendency to lose electrons. However, on going down the group from fluorine to astatine, the ionization energy decreases. This is due to gradual increase in atomic size, which is maximum..
