Question

What is meant by buffer solution?

Answer 1

Hint: A buffer may be a combination of a weak base and an appreciable concentration of the conjugate acid added together. To moderate gross changes in pH, they function. Thus, approx. A buffer would be produced by the equal concentrations of a weak base with its conjugate acid, or the addition of half the same of strong acid to a weak base.

Complete answer:
A solution (more precisely, pH buffer or proton buffer) is a solution consisting of a mix of a weak acid and its conjugate base, or the other way around. Its pH changes little or no when little amount of strong acid or base is added thereto.
Buffer solutions are used as a way of keeping pH at an almost constant value during a big variety of chemical applications. In nature, there are many systems that use buffering for pH regulation. For instance, the bicarbonate buffering system is employed to manage the pH of blood, and bicarbonate also acts as a buffer within the ocean.
a buffer may be a solution which will resist pH change upon the addition of an acidic or basic component. it's ready to neutralize small amounts of added acid or base, thus maintaining the pH of the answer relatively stable. This is often important for processes and reactions which require specific and stable pH ranges.

Note:
A buffer may be a solution containing either a weak acid and its salt or a weak base and its salt, which is immune to changes in pH. Buffers are wont to maintain a stable pH during a solution, as they will neutralize small quantities of additional acid of base.
