Titration of a Weak Acid
You titrated 1.740 g of a solid unknown acid that wasdissolved in 100.0 mL of distilled water; the initial pH value was2.5. You found that pH=pKa=4.2 when 12.50 mL of NaOH hadbeen added. The concentration of the sodium hydroxide was 0.500M.
Calculate the initial percent dissociation of the acidsample.
Calculate the molar mass of theacid.
