The two direct questions form one calculation chain: complete the titre table, average concordant readings, then use Ag+ and BaCl2 stoichiometry to find x.

How this is tested

  • Complete titre tables and calculate a mean titre from concordant readings to 2 d.p.
  • Use mean titre, Ag+ moles and BaCl2 stoichiometry to determine hydrated-salt x.
