Correct answer is option 'A,B,C'. Can you explain this answer? Verified Answer Web15.1.1.1 Chemical reduction method. Several reducing agents, including sodium borohydride, sodium citrate, etc., play a major role as reducing agents in the formation of metal salts into metal nanoparticles. Most of the chemical reactions require an elevated temperature but some reactions will reduce to nanoparticles at room temperature. dカード あとから分割 何回

Web15 Mar 2016 · 2 You are correct, the Pb (s) is oxidized, which makes it the reducing agent. However, there is no change in the oxidation state of the H or the SO4−, so it is not the oxidizing agent. Rather the PbO2 (s) is the oxidizing agent, as the Pb goes from +4 in the PbO2 (s) to +2 in the PbSO4 (s).
