Net Ionic Equation For Precipitation
A student writes the following net ionic equation for the reaction between Pb(NO₃)₂(aq) and KI(aq), which forms a yellow precipitate: Pb²⁺(aq) + 2I⁻(aq) → PbI₂(s). What error, if any, did the student make?
A
K⁺ and NO₃⁻ ions should be included
B
No error; the equation is correctly balanced
C
The coefficient of I⁻ should be 1
D
The state of PbI₂ should be (aq), not (s)
