A weak acid `HA` has `K_(a) = 10^(-6)`. What would be the molar ratio of this acid and its salt with strong base so that `pH` of the buffer solution is `5`?

A certain weak acid has K_(a), = 10^(-5) . If the equilibrium constant for is its reaction with a strong base is repesented as yxx 10^(y) then find the value of y.

Assertion: The pH of a buffer solution does not change appreciably on additions of a small amount of an acid or a base. Reason: A buffer solution consists of either a weak acid and its salt with a strong base or a weak base its salt with a strong acid.

pH of a salt of a strong base with weak acid

pH of a salt of a strong base with weak acid

When a salt of strong base and weak acid is hydrolysed, the resulting solution has :

When a salt of strong base and Weak acid is hydrolysed the resulting solution has :

A buffer solution is made by mixing a weak acid HA (K_(a) =10^(-6)) with its salt NaA in equal amounts. What should be amount of acid or salt that should be added to make 90 mL of buffer solution in which if 0.1 mole of strong acid are added into 1 L of this buffer solution then change in pH is unity ?

For a weak acid, HA pK_a =5. What is the effective range of pH for a buffer comprised of HA and its salt, NaA?
