    Homework Statement How would you use chromatography to determine whether an unknown pure liquid is 1-pentene, cis-2-pentene, or trans-2-pentene? Homework Equations The Attempt at a Solution I looked up the boiling points of the three and see that 1-pentene is lower, but the cis...

    Titration of strong base + weak acid

    I am not sure if I came up with the right answer, but I got a pH of 12.13. I calculated that there were .0015 mols of Ca(OH)2 remaining.

    Titration of strong base + weak acid

    This is the part I am stuck on. When I plug into my ICF chart I get that there are .0225 moles of C6H5COOH. Then I calculate the moles of Ca(OH)2 using .060L X 0.200mol/L and get .012 moles of Ca(OH)2. Do I divide that by 2 because it is a 2:1 reaction? Even if I don't, when I go to subtract...

    Titration of strong base + weak acid

    Homework Statement Consider a titration in which 50.00 mL of .450 M benzoic acid, C6H5COOH, is reacted with 0.2000 M Ca(OH)2. What will the pH be when 60.00 mL of Ca(OH)2 has been added?Homework Equations 2C6H5COOH + Ca(OH)2 -> 2 H2O + Ca(C6H5COO)2The Attempt at a Solution I have determined...
