Answer:

The solution is acidic.

Step-by-step explanation:

To know which option is correct, we shall determine the pH of the solution. This can be obtained as follow:

Concentration of Hydrogen ion [H⁺] = 5.7×10¯⁷ M

pH =?

pH = –Log [H⁺]

pH = –Log 5.7×10¯⁷

pH = 6.2

pH scale reads as follow:

0 to 6.9 => Acidic

7 => Neutral

8 to 14 => Alkaline / basic

The pH of the solution (i.e 6.2) falls between 0 and 6.9 which indicates acidic.

Therefore, the solution is acidic.
