Answer:

Because Water is not a buffer solution and the acetic acid/acetate solution is a buffer solution. An acidic buffer is a solution of a weak acid (acetic acid) and its conjugate base pair (sodium acetate) that prevents the pH of a solution from changing drastically through the action of each component with incoming acid or base.

It usually lasts in place for a maximum of a few days. The stationary front resembles a warm front or a slow cold front. The weather in the stationary front area is variable, often cloudy and often still rainy. In a few days, the stationary front will turn into either a cold or warm front, or its clouds will disintegrate.
