The ionization constant for the given acid solution with 0.010 M concentration whose pH is 6.20 at has to be calculated
Acid ionization constant :
Acids ionize in water. Strong acids ionize completely whereas weak acids ionize to some limited extent.
The degree to which a weak acid ionizes depends on the concentration of the acid and the equilibrium constant for the ionization.
The ionization of a weak acid can be given as follows,
The equilibrium expression for the above reaction is given below.
is acid ionization constant,
is concentration of hydrogen ion
is concentration of acid anion
is concentration of the acid
The concentration of hydrogen ion is measured using scale. The acidity of aqueous solution is expressed by scale.
The of a solution is defined as the negative base-10 logarithm of the hydrogen or hydronium ion concentration.
To Calculate: The ionization constant for the given acid solution with 0.010 M concentration whose pH is 6.20 at
