How much water must be added to 300 mL of a 0.2M solution of CH_(3)COOH for the degree of dissociation of the acid to double ? ( Assume K_(a) of acetic is of order of 10^(-5)M)
Why HF is a weak acid ?
Ph of an acidic solution is:
Name one strong and one weak acid.
In a 0.2 molal aqueus solution of a weak acid HX the degree of dissociation is 0.25. The freezing point of the solution will be nearest to: ( K_(f)=1.86 K kg "mol"^(-1) ) a) -0.26^(@)C b) 0.465^(@)C c) -0.48^(@)C d) -0.465^(@)C
Give two examples of weak acid?
One molal solution of a carboxylic acid in benzene shows the elevation of boiling point of 1.518 K. The degree of association for simerization of the acid in benzene is ( K_(b) for beznene = 2.53 K kg mol^(-1) ):
Ionisation constant of a weak acid (HA) in terms of A_(m)^(oo) and A_(m) is:
