Question

This liquid was combined with anhydrite to create an expanding plaster that broke through a concrete barrier, allowing access to a stash containing gold and platinum on Treasure Island. After the construction of a hydroelectric power plant, several glass bottles of this substance were connected to make a device that later powered a Christmas tree. A self-proclaimed “sorcerer” almost died from this liquid, but was saved in the nick of time by Ginro’s silver spear. This substance was personified as an angelic woman with emerald green hair that occasionally transforms into a horrific skeletal demon, who is named for this substance and the suffix “-ina”. Gas masks were invented to safely collect this caustic substance from a (*) hot spring, which was needed to synthesize a drug to cure the priestess Ruri of pneumonia. For 10 points, name this solution that Senku Ishigami combined with sheets of lead (-5[1])to invent batteries. ■END■ (10[2]0[4])
