PH Adjustments

  1. Sep 16, 2008 #1
    I have a slurry at pH 2. How much CaO must I add to adjust pH to 9.5
    Slurry is in H2SO4 medium

    pH 2 gives you initial concentration of sulfuric acid, pH 9.5 gives you information about excess CaO that have to be added...

    Start by calculate concentration of H2SO4 using the given pH, and use simple stoichiometry to find how much CaO; then add some excess until pH 9 (calculating this theoretically I'm not sure). Should be easy in practice.
