SUMMARY

The discussion centers on balancing the chemical equation Au2(SO4)3 + Ba and identifying the reaction type. The balanced equation is 2Au + 3SO4 + Ba, indicating that barium displaces gold in a redox reaction. Participants emphasize the importance of half-cell reactions for gold (Au) and barium (Ba) to analyze the reaction's feasibility and confirm its redox nature. The sulfate ions are treated as spectator ions in this context.

PREREQUISITES
  • Understanding of redox reactions and their characteristics
  • Knowledge of half-cell reactions and electrochemical potentials
  • Familiarity with balancing chemical equations
  • Basic concepts of ionic compounds and spectator ions
NEXT STEPS
  • Study the principles of redox reactions in detail
  • Learn how to write and balance half-cell reactions
  • Research the electrochemical series for metals, focusing on gold and barium
  • Explore the role of spectator ions in chemical reactions
USEFUL FOR

Chemistry students, educators, and anyone interested in mastering chemical reaction balancing and redox processes.

Please help! :confused:

1. Homework Statement [/b
- I need to complete and balance Au2(SO4)3 + Ba ------>
- what type of reaction is this?
is this a redox reaction?
will the reaction go from left to right?

If the reaction does occur (I don't have the electric potentials of Au and Ba handy) it is indeed a redox reaction. Barium replaces gold...

Write out the half cell reactions for Au+3 and Ba and go from there. Treat the sulfate as a spectator ion.
