## Question:

Which of the following statements is true about buffer solutions.

READ MORE :  Calculate the cell potential E at 25°C for the reaction 2 Al(s) + 3 Fe2+(aq) → 2 Al3+(aq) + 3 Fe(s) given that [Fe 2+] = 0.020 M, [Al 3+] = 0.10 M, and the standard reduction potential is -1.66 V for Al 3+/Al and -0.45 V for Fe 2+/Fe.

The statement that is true about buffer solutions is it: keeps the pH value constant in chemical reaction.

### What is a Buffer Solution?

A buffer solution can be described as an aqueous solution that is made up of a weak acid and a conjugate base, and vice versa.

The pH value of buffer solutions remains almost unchanged when small amount of acid or base is added to the mixture.

A buffer solution can therefore maintain it’s pH value when a small amount of acid or base reacts with it when added. Example of such buffer solutions is, ammonium hydroxide with ammonium chloride.

Therefore, the statement that is true about buffer solutions is it: keeps the pH value constant in chemical reaction.
