Final answer:
To calculate the pH of an aqueous solution with [H+] = 5.20 × 10⁻⁶ M, use the formula pH = -log[H+], which gives a pH of approximately 5.28. The solution is acidic.
Step-by-step explanation:
The question is about calculating the pH level of an aqueous solution. To find the pH of an aqueous solution with a given hydrogen ion concentration, we use the formula pH = -log[H+]. For the given hydrogen ion concentration of [H+] = 5.20 × 10⁻⁶ M, the calculation would be pH = -log(5.20 × 10⁻⁶). This gives us a pH value of approximately 5.28. Since the pH scale ranges from 0 to 14, with 7 being neutral, a pH less than 7 is acidic, and a pH greater than 7 is basic. Therefore, considering the pH scale, a solution with a pH of 5.28 is acidic.
