Unit 5 (bonding & naming)
Review
You need to use a sheet a paper
with this clicker!
1) An unknown black/purple substance is placed in
water and the water turns purple after mixing but
there are also black chunks at the bottom of the
beaker. When the solution is tested with a light
bulb (conductivity) apparatus, the light bulb does
not light up. What type(s) of bond(s) are present in
the substance and explain how you know this.
2) Explain why are substances that contain metallic
bonds such good conductors of electricity.
3) Explain why ionic substances cannot conduct
electricity when not dissolved in water.

interaction occurred in the compound CaCl2 ?
