ou are provided data from a solution which is a mixture of two solutions, solution $1$ and solution $2.$

pH of a mixture solution of solution $1$ and $2=8\mathrm{.}0$

$1$ml of dilute hydrochloric acid $(0\mathrm{.}1$ mol l$-1$ HCl$)$ acid was added to the $100$mls of the solution mixture and the pH re$-$measured.

pH of mixture after adding $0\mathrm{.}1$ mol l$-1$ HCl$=8\mathrm{.}1$

Do you think that the mixture of solution $1$ and $2$ produces an effective buffer, or not? Explain your reasoning in the space below
