    I need to determine the amount of HCl that would be necessary to reduce the pH of a wastewater from pH 5.0 to pH 4.0.

    The wastewater flow is given as 6,056,000 liters/day.

    The HCl is a 40% solution. The specific gravity of the HCl is given as 1.20.

    How do I determine both the mass and volume per unit time of HCl needed to accomplish the change in pH?
