Describe why buffering is needed
WebThe fundamental part of creating a buffer is combining an appreciable amount of a weak acid along with its conjugate base. The first method has the weak acid, acetic acid, but not its conjugate base, acetate. So we need a smaller amount (smaller number of moles) of hydroxide to react with some of the acetic acid to create acetate. Web2 days ago · Views today: 8.57k. A buffer is an aqueous solution that consists of a mixture of a weak acid and its salt (acid buffer) or a weak base with its salt (basic buffer). Its pH changes very little when a small amount of strong acid or base is added to it and is thus used to prevent a solution's pH change. Buffer solutions are used for a wide range ...
