Gen. Chemistry Ionic Equation
« on: October 16, 2007, 06:48:27 PM »
Hello, I'm new here and I am having trouble with a general chemistry question.  I think I might be right, but I want to double check.

2AgNo3(aq) + Na2SO4(aq)  --->  Ag2(SO4) + 2Na(NO3)

Is this Ionic equation correct? 2Ag+(aq) + 2NO3(aq) + Na + SO42 --->  Ag + SO42 + 2Na(NO3)s


Thanks in advance for the help.

Not quite.  Ag2SO4 is insoluble, nitrates are soluble.  Your eqn is also not balanced.

How is it not balanced? I looked over it, and I can't find why it's not.  I see how it's not right, but I can't seem to get the balancing right.  Thank you for responding.

Na+ and Ag+ are not balanced.

the rxn is:
2Ag+ + 2NO3- + 2Na+ + SO42- → Ag2SO4 (s) + 2Na+ + 2NO3-.

Note that nitrate and sodium are spectators.

Now I understand it.  Thanks a lot for the *delete me*
