Worksheet: Uses of Radioisotopes

In this worksheet, we will practice describing the applications of radioisotopes and explaining the importance of decay rate and penetrating power.

Q1:

The dissolution or precipitation of silver(I) chloride in water is an equilibrium process: How could radioactive nuclides be used to show that this reaction is a dynamic equilibrium?

  • AA radioactive sample of A g C l becomes less radioactive when stored in water.
  • BAqueous unstable A g + and C l ions precipitate from a hot aqueous solution to form non-radioactive A g C l .
  • CThe apparent half-life of a radioactive sample of A g C l increases when it is exposed to aqueous unstable A g + or C l ions.
  • DA non-radioactive sample of A g C l becomes more radioactive when exposed to aqueous unstable A g + or C l ions.
  • EA non-radioactive sample of A g C l becomes more soluble when exposed to aqueous unstable A g + or C l ions.
