Chemistry Chemical Reactions Questions Essay Assignment
I’m working on a chemistry question and need guidance to help me learn.
Write a balanced molecular and net ionic equation for all chemical reactions in this experiment.
Step 2: Copper (II) hydroxide from copper (II) nitrate The reaction taking place is aqueous copper (II) nitrate reacting with aqueous sodium hydroxide to give solid copper (II) hydroxide and aqueous sodium nitrate.
Molecular:
Complete Ionic:
Net Ionic:
Step 3: Copper (II) oxide from copper (II) hydroxide The reaction taking place is the decomposition of solid copper (II) hydroxide into solid copper (II) oxide and water with heating
Molecular:
Complete Ionic:
Net Ionic:
Step 4: Copper (II) sulfate from copper (II) oxide The reaction taking place is solid copper (II) oxide reacting with sulfuric acid to produce aqueous copper (II) sulfate and water.
Molecular:
Complete Ionic:
Net Ionic:
Step 5: . Recovery of copper from copper (II) sulfate The reaction which occurs is zinc metal reacting with aqueous copper (II) sulfate to produce copper metal and aqueous zinc sulfate.
Molecular:
Complete Ionic:
Net Ionic:
Side reaction: A second reaction also occurs. Zinc metal reacts with sulfuric acid to yield hydrogen gas and zinc sulfate. Because of this, you must add an excess of zinc metal.
Net Ionic:
Complete Ionic
