This is a lab concerning activity serious of metals and calculation of electrode portentions...
Complete the following: if there is NO reaction write NR:
(They provided the reactants, my answer is the products)
Iron(s) + copper sulfate(aq) → iron sulfate(aq) + copper(s)
Zinc(s) + calcium chloride(aq) → NR
Silver(s) + copper nitrate(aq) → NR
Chlorine(aq) + potassium bromide(aq) → potassium chloride(aq) + bromide(s)
Iodine(aq) + sodium bromide(aq) → NR
For the reactions that work, I had to write chemical equations and net ionic equations:
(chem eq) Fe(s) + CuSO4(aq) → FeSO4(aq) + Cu(s)
(ionic eq) Fe(s) + Cu2+(aq) → Fe2+(aq) + Cu(s)
(chem eq) Cl(aq) + KBr(aq) → KCl(aq) + Br (aq)
(ionic eq) (Don't know)
Can my answers please be checked? And can I please get help on the ionic equation involving chlorine and potassium bromide?
THanks
Iron(s) + copper sulfate(aq) �¨ iron sulfate(aq) + copper(s)
ok
Zinc(s) + calcium chloride(aq) �¨ NR
ok
Silver(s) + copper nitrate(aq) �¨ NR
ok
Chlorine(aq) + potassium bromide(aq) �¨ potassium chloride(aq) + bromide(s)
potasium chloride(aq) + BROMINE(aq). Actually, bromine is not all that soluble in water and I am tempted to write bromine(l) for only a limited amount will dissolve.
Iodine(aq) + sodium bromide(aq) �¨ NR
ok
For the reactions that work, I had to write chemical equations and net ionic equations:
(chem eq) Fe(s) + CuSO4(aq) �¨ FeSO4(aq) + Cu(s)
(ionic eq) Fe(s) + Cu2+(aq) �¨ Fe2+(aq) + Cu(s)
ok
(chem eq) Cl(aq) + KBr(aq) �¨ KCl(aq) + Br (aq)
Cl2 + KBr(aq) ==> KCl(aq) + Br2(l)
(ionic eq) (Don't know)
Cl2 + Br^- ==> 2Cl^-(aq) + Br2(l)
Can my answers please be checked? And can I please get help on the ionic equation involving chlorine and potassium bromide?
I see I didn't get (aq) on some of them.
Your answers are mostly correct. Here is the correct version:
Iron(s) + copper sulfate(aq) → iron sulfate(aq) + copper(s)
Chemical equation: Fe(s) + CuSO4(aq) → FeSO4(aq) + Cu(s)
Net ionic equation: Fe(s) + Cu2+(aq) → Fe2+(aq) + Cu(s)
Zinc(s) + calcium chloride(aq) → No reaction (NR)
Silver(s) + copper nitrate(aq) → No reaction (NR)
Chlorine(aq) + potassium bromide(aq) → potassium chloride(aq) + bromine(l)
Chemical equation: Cl2(aq) + 2KBr(aq) → 2KCl(aq) + Br2(l)
Net ionic equation: Cl2(aq) + 2Br-(aq) → 2Cl-(aq) + Br2(l)
Iodine(aq) + sodium bromide(aq) → No reaction (NR)
You did not include (aq) in some of the equations, so I corrected that for you. Also, for the reaction between chlorine and potassium bromide, I have provided the correct net ionic equation for you.
