Like other metals, magnesium is malleable and is a good conductor of electricity.
Explain why magnesium is malleable.
Explain why magnesium is a good conductor of electricity.
Copper and iron both form chlorides. One is copper(II) chloride with the formula CuCl2\text{CuCl}_2CuCl2, and the other is iron(III) chloride with the formula FeCl3\text{FeCl}_3FeCl3.
The addition of sodium hydroxide solution can be used to distinguish between solutions of these chlorides.
State what would be observed in each case.
CuCl2\text{CuCl}_2CuCl2:
FeCl3\text{FeCl}_3FeCl3:
Write a chemical equation for the reaction of copper(II) chloride (CuCl2\text{CuCl}_2CuCl2) with sodium hydroxide solution.
