Identify if a reaction is likely to occur, and write a net ionic equation:
a) Chromium dipped into silver nitarte
b) Gold immersed into hydrochloric acid
The Attempt at a Solution
a) Cr(s) + 3AgNO3(aq) ---> Cr(NO3)3(aq) + 3Ag(s)
Cr(s) + 3Ag(aq) + 3(NO3)(aq) ---> Cr(aq) + 3NO3(aq) + 3Ag(s)
Cr(s) + 3Ag(aq) ---> Cr(aq) + 3Ag(s)
I'm pretty sure this is right.... but could anyone confirm? I think it's just an example of ionic displacement right?
b) From doing some research I think that no reaction will occur with gold and sulfuric acid, but why is this? Can anyone hep me out with where I should be referencing this information? Thanks.
