Example on page 50 in Course Reader

Postby Jasmine_Brownfield_3E » Sun Feb 12, 2017 9:43 pm

On page 50 of the course reader, the example of a gold ring being tested to dissolve in Nitric Acid is given.
"Will a gold ring dissolve in 1M Nitric Acid (HNO_3) to form a 1M Au(3+) solution?"

After finding the value of delta_G°(redox), how would you know that the gold does not dissolve in the nitric acid? What value would it need to be to dissolve?

delta_G°(redox) = +1.56 x 10^5 J

Gold will not dissolve when delta G is positive because it will be a non-spontaneous process.
