what 75% sarpong.7@wright.edu aq Part 3 (1 pt) Feedback See Hint What will happen if we combine the solution of sodium iodide and the solution of lead(I) nitrate? The solutions will mix, so all of the ions wil be evenly distributed throughout the entire solution. But sometimes mixing solutions containing dissolved ions leads to a precipitation reaction: the formation of a new insolublecompound. To determine if this happens, we refer to the solubility rules for common ionic compounds in water (Table 4.4, p. 170). Based on the information presented in that table, complete the balanced overall ionic equation for the mixing of these two solutions. X, He-* . (aq). 2Na" (ag) + 21_ (aq)-Pb2+ (aq)-2NOg (ay), Pbl (5) +2Na (aq) 2NOj (a) 04/06 >Explanation / Answer
The overall ionic equation has been depicted correctly in the picture :
2Na+(aq) + 2I-(aq) + Pb2+(aq) + 2NO3-(aq) = PbI2(s) + 2Na+(aq) + 2NO3-(aq)
The spectator ions are cancelled from the overall ionic equation to get the net ionic equation as :
Pb2+(aq) + 2I-(aq) = PbI2(s)
