In a certain experiment, two aqueous solutions are mixed. Solution A has a pH of 3, and Solution B has a pH of 8. When these two solutions are combined in equal volumes, the resulting pH of the mixture is affected by the properties of acids and bases. Given that Solution A is acidic and Solution B is basic, determine the final pH of the mixture.
Recall that pH is a logarithmic scale that measures the concentration of hydrogen ions in a solution, with lower values indicating more acidic solutions and higher values indicating more basic solutions.
