    Answer:

    pH = 3.3

    Explanation:

    Step 1: Given data

    Concentration of hydronium ions in the agricultural product ([H₃O⁺]): 4.7 × 10⁻⁴ M

    Step 2: Calculate the pH of the agricultural product

    We will use the definition of pH.

    pH = -log [H₃O⁺]

    pH = -log 4.7 × 10⁻⁴

    pH = 3.3

    Since the pH < 7, the agricultural product is acidic.
