A weak acid HA after treatment with 12 ml of 0.1M strong base BOH has a PH of 5 . At the end point the volume of same base required is 26.6 ml .what is the value K_a acid ?

The pH of basic buffer mixtures is given by : pH=pK_(a)+log((["Base"])/(["Salt"])) , whereas pH of acidic buffer mixtures is given by: pH= pK_(a)+log((["Salt"])/(["Acid"])) . Addition of little acid or base although shows no appreciable change for all practical purpose, but since the ratio (["Base"])/(["Salt"]) or (["Salt"])/(["Acid"]) change, a slight decrease or increase in pH results in. A weak acid HA after treatment with 12 mL of 0.1M strong base BOH has a pH=5 . At end point, the volume of same base required is 26.6mL K_(a) of acid is:

A weak acid HX, after mixing with 12 mL of decimolar potash has a pH 5. At the end point of neutralisation 26.6 mL of potash is consumed. What is the dissociation constant of HX ?

A weak base (BOH) with K_(b) = 10^(-5) is titrated with a strong acid (HCl) , At 3//4 th of the equivalence point, pH of the solution is:

A weak base (BOH) with K_(b) = 10^(-5) is titrated with a strong acid (HCl) , At 3//4 th of the equivalence point, pH of the solution is:

A weak base BOH is titrated with strong acid HA . When 10mL of HA is added, the pH is 9.0 and when 25mL is added, pH is 8.0 . The volume of acid required to reach the equivalence point is
