Consider a solution formed by mixing 58.0 mL of 0.100 M H2SO4, 37.0 mL of 0.100 M HOCl, 25.0 mL of 0.200 M NaOH, 25.0 mL of 0.100 M Ca(OH)2, and 10.0 mL of 0.150 M KOH. Calculate the pH of this solution?
I am trying to understand the effects of leachate from landfills and its effects on groundwater, and since I am in environmental health- its effects on the human health.
A solution is prepared at 25 degrees Celsius between 150 mL of 0.15 M C6H5COOH and 12.5 grams of C6H5COONa. What is the resultion pH of the solution, assuming no volume change.
An aliquot of 14.045 grams of this solution is titrated with 0.1043 M hydrochloric acid (HCl.) and it required hydrochloric acid (HCl solution) of 29.18 mL to reach the methyl red endpoint. Compute the weight % Ammonia (NH3) in the aqueous waste.
