2. What solution is used to test for sulfate ions?

  • Barium chloride
  • Calcium chloride
  • Strontium chloride
  • Magnesium chloride

3. How do we test for halide ions?

  • Add dilute nitric acid followed by silver nitrate solution and see if a precipitate forms.
  • Add dilute sodium hydroxide solution to see if a precipitate forms.
  • Add dilute hydrochloric acid followed by barium chloride to see if a white precipitate forms.
  • Perform a flame test.

4. When a reversible reaction is at equilibrium, how does the rate of the forward reaction compare with the rate of the reverse reaction?

  • The reverse reaction occurs at a faster rate than the forward reaction.
  • The forward reaction and and reverse reaction occur simultaneously at the same rate.
  • The forward reaction occurs at a faster rate than the reverse reaction.
  • It depends on the reaction conditions.

5. The equation for finding the mass of a titrated substance in moles is...

  • ...volume in dm3 x concentration in mol/dm3.
  • ...concentration in mol/dm3 x volume in dm3.
  • ...concentration in mol/dm3 / volume in dm3.
  • ...volume in dm3 / concentration in mol/dm3.




Very good though some of the questions i haven't covered.
