Problem 110IE

IE: 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?

Step-by-Step Solution:
Step 1 of 3

Solution 110 IE: Step1: Given, mass of the lead crystal = 286 g Therefore, mass of PbO in the crystal = (27/100) x 286 g = 0.27 x 286 g = 77.22 g Molar mass of PbO = 223.20 g/mol Therefore, number of moles of PbO in the crystal = mass of PbO / molar mass = 77.22 / 223.20 = 0.346 mol Step2: Sodium sulfide reacts with PbO to give the following reaction: Pb + Na S2 PbS + 2Na + Now, to decontaminate 1 mol...
