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.
<h3>What is conventional theory of the formation of the galaxy ?</h3>
The conventional theory of the formation of the galaxy can be regarded as one that stressed that the formation of milky way was done relatively short time some million years ago.
And this was when spherical cloud of gas collapsed as a result of pressure the particular gravity which was surrounded by a halo.
Therefore, formation of the galaxy was recorded to occur roughly 12 to 13 billion years ago .
