Golden Rain Experiment

The name of the precipitate formed in this experiment is:

• Lead (II) nitrate

• Potassium iodide

• Lead (II) iodide

• Potassium nitrate

The colour of the solid formed during the golden rain experiment is:

• Blue

• White

• Yellow

• Colourless

Which of the following is added after dissolving lead(II) nitrate?

• Water

• Sodium hydroxide solution

• Copper (II) sulfate solution

• Hydrochloric acid

What is the chemical formula of lead(II) iodide?

• KI

• PbI2

• KNO3

• Pb(NO3)2

Heating the solution cause the (a)   to increase.

The reaction occur in the golden rain experiment is called:

• Double displacement reaction

• Displacement reaction

• Substitution reaction

• Addition reaction

Double displacement reaction often result in a product that is a (a)   .

Which factor(s) can affect the rate of crystal formation in the Golden Rain experiment?

• Temperature

• Concentration of reactants

• Stirring speed

• All of the above

We should wear protective gloves in this experiment because lead(II) iodide is (a)  

As the solution cools down, the dropping temperature forces lead iodide to precipitate back out of solution.

• True

• False
