hope it helped,please let me know!!!
It means there is a lot of the same thing and not many others

Answer:
pv=nrt solution re solve it
The solution shows only a small change in its pH when a strong acid or base is added and the solution resists change in its pH only when a weak acid or base is added to it are the characteristic properties the buffered solutions possess.
Options B and C
<u>Explanation:</u>
A solution is precipitated by the presence of weaker acid and its joint base (or vice versa). Buffer solutions are used to maintain the pH level of a chemical reaction at a constant level.
The solution shows only a small change in its pH when small amount of strong base or acid is added. Solutions resist any change in its pH when a weak base or acid is added. The buffer solution's pH is affected only when a certain concentration of bases or acids is added.
