Question

how are basic buffer solution prepared​

Answer 1

Basic buffer has a basic pH and is prepared by mixing a weak base and its salt with strong acid. The aqueous solution of an equal concentration of ammonium hydroxide and ammonium chloride has a pH of 9.25. ... An example of an alkaline buffer solution is a mixture of ammonium hydroxide and ammonium chloride (pH = 9.25).

Answer 2

Answer:

A basic buffer is prepared using a weak base and its salt. The classic example is ammonia solution and ammonium chloride. The pOH of the solution may be calculated using the pkb value of ammonia (4.75), or the Kb of ammonia (1.78 x 10-5). Once the pOH is found, the pH is calculated using the relationship pH + pOH = 14.
