Question

What will be the ph of a buffer solution containing an acid of pka 7. 5, with an acid concentration exactly one fourth of that of the conjugate base?

Answer 1

8.1  will be the pH of a buffer solution containing an acid of pka 7. 5, with an acid concentration exactly one-fourth of that of the conjugate base.

In chemistry, the pH scale is used to define the acidity or basicity of an aqueous solution. Historically, pH stood for the "potential of hydrogen." The pH values of acidic solutions are typically lower than those of basic or alkaline solutions.

A weak acid and the conjugate base of the weak acid, or a weak base and the conjugate acid of the weak base, are combined to form the buffer solution, a water-based solvent solution. They withstand being diluted or having modest amounts of acid or alkali added to them without changing their pH.

A weak base and its salt are combined with a strong acid to create a basic buffer, which has an acidic pH. the aqueous mixture of ammonium hydroxide and ammonium chloride, both in equal concentrations.
