Aluminum (metal) is insoluble. In metallic form it Al is rather conductive.
Aluminium hangers do conduct electricity, as aluminium is a good conductor of electricity. The reason you may not experience an electric shock when touching an aluminium hanger is because it is often coated with a non-conductive material, such as paint or plastic, which prevents direct contact with the aluminium.
A solution containing ions conduct electricity. They are different for each solution.
Aluminium is a good conductor of electricity and heat.
A solution containing ions conduct electricity.
A solution which can conduct electricity is known as an electrolyte.
A solution of NaCl in a solvent in which the cations and anions separate, for example in water, can conduct electricity.
An ionic compound can conduct electricity when it is in solution or melted.
Sulfur does not conduct electricity in aqueous solution. This is because sulfur in its elemental form is a non-metal and is a poor conductor of electricity. In aqueous solution, sulfur does not exist as an ionic or free electron-carrying species that would allow it to conduct electricity.
Aluminium is a good thermal and electrical conductor, having 62% the conductivity of copper...
Acid solutions conduct electricity.
A water solution containing ions conduct electricity.
