Question
Many ionic compounds are water soluble, so, for example, we can make solutions of sodium iodide, NaI, and lead(II) nitrate, Pb(NO3)2, by simply dissolving the ionic solids in water. In the process of dissolving, the ions from the ionic solutes (sometimes referred to as salts) are split apart and hydrated (surrounded) by water molecules.
We represent the species in the sodium iodide solution as Na+(aq) and I–(aq), and in the lead(II) nitrate solution as the species Pb2+(aq) and NO3–(aq).
Complete the balanced overall ionic equation for sodium iodide dissolving in water. Nal(s) -----
Complete the balanced overall ionic equation for lead(II) nitrate dissolving in water. Pb(NO3)2(s) (3 and 2 are lowered)
Explanation / Answer
The balance ionic equation for---
Sodium iodide dissolving in water =
NaI(s) --> Na+(aq) + I-(aq)
Lead(II)nitrate dissolving in water =
Pb(NO3)2(s) --> Pb2+(aq) + 2NO3-(aq)
