Manganese Chloride Lab
Mass your piece of manganese and record below. Balance each equation. Then, using your mass of manganese,
calculate the theoretical mass of manganese chloride that can be produced for each hypothetical reaction.
Theoretical mass of product
Mn(s) + HCl(aq) 
MnCl(aq)
+
H2(g)
_____________ g MnCl
Mn(s) + HCl(aq) 
MnCl2(aq)
+
H2(g)
_____________ g MnCl2
Mn(s) + HCl(aq) 
MnCl3(aq)
+
H2(g)
_____________ g MnCl3
Mn(s) + HCl(aq) 
MnCl4(aq)
+
H2(g)
_____________ g MnCl4
Mn(s) + HCl(aq) 
MnCl7(aq)
+
H2(g)
____________ g MnCl7
Mass the empty flask and then place the piece of manganese in the flask and react with an excess of 7M HCl.
When the reaction is complete, boil off the excess acid until completely dry.
Data Table:
Mass of manganese metal
mass of empty, dry flask
Mass of dry product + flask
Mass of just the dry product
What is your product?
Explain any difference between the actual and theoretical mass of your product.
