How are basic buffers prepared?
Basic buffer is prepared by mixing a weak base with its conjugate salt along with a strong acid. Complete step by step answer: As we know, a buffer solution is used to maintain the pH of a solution at a constant value during titration when a small amount of acid or base is added to the solution.
