Explanation:

What is meant by yield buffer ?

A weak acid and its conjugate base, or a weak base and its conjugate acid, are combined to create a buffer. For instance, a buffer solution would be created when the salt NaF and weak acid HF were mixed.

A buffer is a substance that can withstand a pH change when acidic or basic substances are added. Small additions of acid or base can be neutralised by it, keeping the pH of the solution largely constant. For procedures and/or reactions that call for particular and stable pH ranges, this is significant.

A portion of main memory called the buffer is utilised to temporarily store or keep data. In other terms, a buffer stores data that is transferred between two devices or an application. The act of buffering involves temporarily storing data in a buffer.
