vi.
Repeat addition of 1 mL of the 0.1 M NaCl solution from the burette into the unknown
solution until the mass of AgCl doesn't change any more. Record the mass of the
precipitate AgCl on the Data Sheet.
Data Sheet
Volume of the original unknown AGNO3 solution =
mL
Mass of AgCl (s) =,
Mole of AgCl =
(mole = mass /molar mass)
Calculate mole of AGNO3 in the 10 mL unknown solution based on the following reaction
equation:
NaCliag) + AGNO3(aq) → NANO3(aq) + AgCls)
Mole of AGNO, in the 10 mL unknown solution =
use the coefficient ratio)
_(hint,
Mass of AGNO3 in the 10 mL unknown solution =
(mass = mole x molar mass)
Calculate mass of AGNO, in the original unknown solution as follows:
Mass of AGNO, in the original unknown solution
= Mass of AGNO, in the 10 mL unknown solution x
volume of the unknown AGNO3 solution in ml.
