What is the chemical equation for reducing Tetraamine copper(II) culfate with magnesium? The lab talks about adding HCl to dissolve the excess magnesium solids and see the hydrogen gas being released the product of this equation is supposed to give us our solid copper back?

Homework Answers

Answer #1

Tetraamine copper(II) sulfate is Cu(NH3)4SO4 (tetramine means it has 4 amine NH3 group and Cu in +2 state, Sulfate for SO4 group) and when it reacts with magnesium Mg we have the following reaction -

Cu(NH3)4SO4 + Mg -> Cu + MgSO4 + 4NH3

solid Cu (copper) gets deposited at the bottom of the beaker

Here. if we take Mg in excess we need to dissolve the excess by adding HCl so, the following reaction will take place -

Mg + 2HCl -> MgCl2 + H2

Releases H2 gas.

Chemical Reactions Types and Their Equations Making Heat with Chemical Reactions Have you ever wondered how an instant heat pack works? A disposable heat pack works by a chemical reaction that combines iron in the package with oxygen from the air when the outer packaging is removed producing iron oxide. You have probably seen the product of this reaction in what is commonly called rust. The reaction releases heat, which allows the pack to reach a sufficient temperature that is...

Below is the background info for the lab assignment. The 4 blank boxes are the questions I would like answers too. The end point for the fine titration was 35.90 mL in the burette when the solution turned bright green again. And the coarse titration I got 35.36mL as the end point. 35.9 mL is exact in case you need that info. Thanks!
