Pasting oils used with carbon can also be added to these substances, yielding an extrudable electrode that is dipped to form a meniscus before use. For 10 points each:
[10m] Name these alloys that serve as alternatives to aqueous solvent for dispersed delivery of metals. Historically, these alloys were used as reducing agents, but today, they are better known for their use in dentistry.
ANSWER: amalgams (“uh-MAL-gam’s”) [accept dental amalgam; accept paste amalgam electrodes]
[10e] Zinc amalgam is used in the Clemmensen reduction, which requires this strong acid. This acid reacts with sodium hydroxide to form salt water.
ANSWER: hydrochloric acid [or HCl]
[10h] This compound is the skeleton of several neutral organic reducing agents like the tetraaza- (“tetra-AY-zuh”) “Super-Electron Donors” of the Murphy lab. Derivatives of this compound with four chalcogens (“KAL-kuh-jens”) are paired with BEDT (“B-E-D-T”) or TCNQ in Fabre and Bechgaard (“BECK-gard”) salts.
ANSWER: fulvalene (“FULL-vuh-leen”) [accept tetrathiafulvalene or TTF or (tetramethyl)tetrathiafulvalene; accept (tetramethyl)tetraselenafulvalene; accept tetraazafulvalene]
