48 Given the balanced ionic equation representing a reaction: Cu(s) + 2Ag+(aq) → Cu^2+(aq) + 2Ag(s)

During this reaction, electrons are transferred from (1) Cu(s) to Ag+(aq)

(2) Cu^2+(aq) to Ag(s)

(3) Ag(s) to Cu^2+(aq)

(4) Ag+(aq) to Cu(s)

Solution: According to the reaction, Cu becomes Cu^2+ which means it loses 2 electrons. Ag+ becomes Ag which means it gains an electron. The electrons must be traveling from Cu to Ag+
