Question:
Lead glass contains 18–40% by mass of PbO (instead of CaO in regular glass). Lead glass is still used industrially, but “lead crystal” drinking goblets are no longer considered safe, as the lead may leach out and cause toxic responses in humans. A particular 286-g lead crystal goblet that holds 450 mL of liquid is 27% PbO by mass, and it leaches 3.4 micrograms of lead every time it is filled. How many grams of sodium sulfide would be required to decontaminate all the lead in the entire goblet?
