Solution: Which statement is most true of the reaction:Bi2S3 (s) + 3 H+ (aq) → 2 Bi3+ (aq)+ 3 H2S (aq)a) This is a redox reaction because Bi2S3 serves as the oxidizing agent and H+ as the reducing agentb) This is a redox reaction because Bi2S3 serves as the reducing agent and H+ as the oxidizing agentc) This is a redox reaction because Bi is oxidized and H is reducedd) Both a and c are truee) None of the above are true because the reaction is not a redox reaction  

Problem

Which statement is most true of the reaction:

Bi2S3 (s) + 3 H+ (aq) → 2 Bi3+ (aq)+ 3 H2S (aq)

a) This is a redox reaction because Bi2Sserves as the oxidizing agent and H+ as the reducing agent

b) This is a redox reaction because Bi2S3 serves as the reducing agent and H+ as the oxidizing agent

c) This is a redox reaction because Bi is oxidized and H is reduced

d) Both a and c are true

e) None of the above are true because the reaction is not a redox reaction
