how can we determine d strength of an acid
Asked by shuchi.saumya | 23rd Jul, 2010, 12:00: AM
For an aqueous solution of acid or base product of H+ ion concenteration and (OH)-ion concenteration is alwaya constant and equals to 10-14 which is called ionic product of water (Kw).
strenght of an acid could be determined by the negative logarithm of hydrogen ion concenteration ie. pH of the solution.
ex. if the solution has H+ ion concenteration = 0.2 M ie.10-2 moles/litre, its pH is 2.
Asubstance is considered acidic if its ph lies between 0 to 6.
