The of formic acid 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
Freezing point Depression: ( )
The difference between the freezing point of a pure solvent and solution of solute in the same solvent.
= molal freezing point constant
m = molality
To Calculate: The of formic acid at
