f 27.0 mL of Ca(OH)2 with an unknown concentration is neutralized by 32.40 mL of 0.185 M HCl, what is the concentration of the Ca(OH)2 solution? Show all of the work needed to solve this problem.
Ca(OH)2 + 2 HCl 2 H2 O + CaCl2.

  • Chemistry - ,

    Ca(OH)2 + 2HCl ==> 2H2O + CaCl2.

    1. moles HCl = M x L = ??
    2. Using the coefficients in the balanced equation, convert moles HCl to moles Ca(OH)2.
    3. Then M Ca(OH)2 = moles Ca(OH)2/L Ca(OH)2
