Determination of % KPH in unknown mixture
Trail 1:
mass of sample: 0.600 g
buret reading
final: 16.00 mL
initial: ?
NaOH used: ?
Trail 2:
mass of sample: 0.600 g
buret reading
final: 15.50 mL
initial: ?
NaOH used: ?
Trail 3:
mass of sample: 0.600 g
buret reading
final: 15.80 mL
initial: ?
NaOH used: ?
find initial buret reading for trail 1,2,and 3.
calculate mass of KPH and percent KPH.
If c(NaOH) = 0.1M:
%KHP = 53.67%
