Clarkson; Roger LeRoy Miller; Frank B. However, as NaOH was added further, there came a point when no amount of stirring changed the pink colour. This can be found by dividing the molar mass of KHP into the mass of KHP (.568/204-the mass,gram units, cancel and moles remain if you use the dimensional analysis method).

[c] NaOH = n/V = (0.00979/0.0950) = 0.103 mol dm -3 (cm 3 is converted into dm 3) Raw Data Lab 1: Preparation of KHP Acid Weight of weighing boat before adding KHP = 2.67 g Weight of weighing boat with KHP = 4.67 g The uncertainty of 2.57% indicates that my values were accurate up to within 2.57%. The percentage uncertainty calculated of the concentration of NaOH was 2.57%, which indicates that the level of precision, although not low, could have been better. The higher molarity of the acid compared to the base in this case means that a smaller volume of the acid is required to reach the equivalence point. { "21.01:_Properties_of_Acids" : "property get
