Question

Define buffer
explain it

Answer 1

Answer:

A buffer is a solution that can resist pH change upon the addition of an acidic or basic components. It is able to neutralize small amounts of added acid or base, thus maintaining the pH of the solution relatively stable.

$<p style="color:purple; font-family:cursive; bacground:white;font size35px;">. A buffer is a solution containing either a weak acid and its salt or a weak base and its salt, which is resistant to changes in pH. In other words, a buffer is an aqueous solution of either a weak acid and its conjugate base or a weak base and its conjugate acid.$

$<p style="color:purple; font-family:cursive; bacground:white;font size35px;">.A buffer contains data that is stored for a short amount of time, typically in the computer's memory (RAM). The purpose of a buffer is to hold data right before it is used.$

A buffer consists of a weak acid and its conjugate base, or a weak base and its conjugate acid.$
