Exp 210 CYCLE OF COPPER REACTIONS Part 1: Reaction of solid copper with concentrated nitric acid Observations: (partial example given) Tke copper wire was bright/shiny after cleaning wits steel wool. The nitric acia solution. was nearly clear/coloriess olthongh α very faint reddish brown discoloration was evident. Reaction Products The cemplet d Balanced molecular chemical equation (this first reaction equation is given as an example) What ions are in solution after the reaction is complete? What is the oxidation state of the copper reactant? What is the oxidation state of the copper product? Reaction Classification Part 2: Reaction of copper(Il) nitrate with sodium hydroxide solution Observations Balanced molecular chemical equation for the coppertll) nitrate+ sodium hydroxide reaction What ions are in solution after the reaction is complete? What is the oxidation state of the copper reactant? What is the oxidation state of the copper product? Primary Reaction Classification: preci addition to reacting with the copper nitrate, the sodium hydroxide will also react with excess nitric acid left over om the Part 1 reaction. Write the balanced molecular chemical equation for this reaction and classify this action alanced molecular chemical equation for the nitric acid+ sodium hydroxide reaction condary Reaction Classification: EXP 210 CYcLE or COPPER REACTONS PAGE 3 of 6 Part 3: composition of coppe(I) hydroxide with heat Observations a.a Balanced molecular chemical equation for this reaction What is the chemical name and formula of the precipitate? What ions are removed from the precipitate by washing? steps.) Hint: considered the ions that are in excess or otherwise left over from the previous What is the oxidation state of the copper reactant? What is the oxidation state of the copper product? Reaction Classification:desnpasiet Part 4: Reaction of copper(II) oxide with sulfuric acid Observations sulfuric acid reaction alanced molecular chemical equation for the copper(l) oxide hat ions are in solution after the reaction is complete? at is the oxidation state of the copper reactant? at is the oxidation state of the copper product? action Classification: acs EXP 210 CYCLE OF CGOPPER REAC TIONS art 5: Reaction of copper(lI) sulfate with zinc solid Observations Balanced molecular ch Note: the from the previous step- it is not a product of this reaction emical equation for the copper(lI) sulfate zinc reaction before HC(aq) is added g this reaction is due to a side reaction between zinc and the excess sulfuric acid e gas produced durin What is the oxidation state of the copper reactant? What is the oxidation state of the copper product? Primary Reaction Classification dition to reacting with the e copper(ll) sulfate, the zinc will also react with excess sulfuric acid left over from the t Part 4 reaction as Balanced molecular chemical equation for the zinc+ sulfuric acid reaction noted above. Write the balanced molecular chemical equation for this reaction Give the name and formula of the gas evolved? What is the oxidation state of the zinc reactant? What is the oxidation state of the zinc product? Secondary Reaction Classification: Hydrochloric acid was added to remove excess zinc from the desired solid product. Write the balanced molecular chemical equation for this reaction and classify this reaction. Balanced molecular chemical equation for the zinc + hydrochloric acid reaction Give the name and formula of the gas evolved? What is the oxidation state of the zinc reactant? What is the oxidation state of the zinc product? Secondary Reaction Classification net ionic form of the chemical equations for the two zinc + acid reactions. It may be helpful to write the ionic form of these equations on a separate sheet to guide you when writing the net ionic form. Zn(s) + H2S04(aq) rxn Zn(s) + HCI(aq) rxn Notice any similarities? (This is a rhetorical question.)
