  What would happen if HCl was added to manganese?

  I think it reacts moderately fast with HCl since magnesium>manganese>carbon>zinc in order of reactivity. May I know whether what I have said is correct?

   

  Just to ask, can you make cans and containers using steel material? I don't think it is suitable or is it?

   

   

   

   

  Lots of thanks.

  Lets say you are given the following choices:

   

  Cast iron for woks

  galvanised steel for cutlery

  stainless steel for hosptal equipment

  steel for cans & containers

   

  i think the least compatible choice is the last one.

  agree it's not as good a choice.. but in some countries, there's still a certain percentage of steel in the cans..

  Yes, manganese would react with acids.

   

  Mn  -->  Mn2+  + 2e-  (+1.18V)

  2H+  +  2e-  -->  H2   (+0.00V)

   

  For standard (1.0 mol/dm3) molarities, the above reaction is feasible.

   

   

  Regarding the "steel cans" question, have a read :

  "Paul Ding" makes a good point - in the real world, it's not just science which determines the way things are run. This is especially true for medical science.

  Steel is also more expensive than aluminium. That is y most cans are made off aluminium. Another factor u need to consider for cans are, the material should not corrode so easily..
