Calculations:
Concentration of potassium hydrogen phthalate (KHP)
Word equation:
Potassium hydrogen phthalate + sodium hydroxide →Potassium sodium phthalate
+ water
Molecular equation:
KHC8H4O4(aq) + NaOH →KNaC8H4O4 + H2O
Molar mass of KHP (Mr) = 39 + (12x8) + 5 + (16x4) = 204
Mass of boat + KHP = 4.87 g
Mass of boat after transfer: 0.86 g
Mass of KHP transferred (m) : 4.87 - 0.86 = 4.01 g
Moles of KHP: (n = m/Mr) 4.01 ፥ 204 = 0.0197 mol to 3 sf
Volume of solution in volumetric flask (v) : 250 ፥ 1000 = 0.25 dm-3
