Question 14 of 18 ncorrect Map Sapling Learning Write the balanced equation for the reaction of aqueous Pb(CIO3)2 with aqueous Nal. Include phases Pbl, 2NaCIO, 312 What mass of precipitate will form if 1.50 L of highly concentrated Pb(CIO3)2 is mixed with 0.100 L of 0.290 M Nal? Assume the reaction goes to completion.

Explanation / Answer

Pb(Cl3)2 (aq) + 2 NaI (aq) —> PbI2 (s) + 2NaClO3 (aq)

since Pb(ClO3)2 is highly con concentrated, the limiting reagent will be NaI

mol of NaI = M*V

= 0.290 M * 0.100 L

= 0.0290 mol

from reaction,

mol of PbI2 formed = (1/2)*mol of NaI reacted

= (1/2)*0.0290 mol

=0.0145 mol

molar mass of PbI2 = 461 g/mol

mass of PbI2 = number of mol * molar mass

= 0.0145 mol * 461 g/mol

= 6.68 g

Answer: 6.68 g
