Scenario:
A large (pure iron, Fe) nail is placed in a beaker containing a green solution (nickel (II) chloride (NiCl2)). After several hours there are chunks of a silver-coloured solid on the bottom of the beaker and the solution is now yellow, and the nail appears to be smaller. There were no bubbles.
Possible Ideas:
- Iron bonded with nickel, creating silver-coloured solid. The chlorine is the yellow solution.
- Iron bonded with chlorine, creating silver-coloured solid. The nickel is the yellow solution.
Iron bonded with nickel chloride compound (iffy, need two products, this produces one)- Iron bonded with nickel, creating yellow solution. The chlorine is the silver-coloured solid.
- Iron bonded with chlorine, creating yellow solution. The nickel is the silver-coloured solid.
Necessary Questions/ Information:
- What does nickel and chlorine look like when pure?
- Is either nickel or chlorine a solid or liquid when pure?
- How many bonds do the each of the three elements make?
- Ways to check for presence of elements in solid and solution after reaction
- Is there a way to separate the elements of the solution from before the reaction?
These are necessary components because they allow us to find the number of atoms of each element to balance an equation or have the necessary number of atoms on a particle diagram.
Necessary Measurements:
- Mass of iron nail before and after reaction
- Mass of solution before and after
- Mass of silver-coloured solid
These are necessary components of the experiment because they allow us to convert these measurements into moles to find the rations of the new molecules following the reaction, allowing us to make accurate and correct particle diagrams and equations.
