Question

Determine if HNO3(aq) can dissolve each metal sample.

Standard Electrode Potentials at 25 ∘C

Reduction Half-Reaction		E∘(V)
NO3−(aq)+4H+(aq)+3e−	→NO(g)+2H2O(l)	0.96
Au3+(aq)+3e−	→Au(s)	1.50
Cu2+(aq)+2e−	→Cu(s)	0.34
Sn2+(aq)+2e−	→Sn(s)	-0.14

A) Write a balanced chemical reaction showing how the 4.11 g Sn dissolves in HNO3(aq).

B) Determine the minimum volume of 6.1 molL−1 HNO3(aq) required to completely dissolve the sample.
