Question

Write the net ionic equation for the precipitation of silver iodide from aqueous solution:?

Answer 1

`Ag^(+) + I^(-) rarr underbrace(AgI(s)darr)_"yellow salt"`

Explanation:

The complete ionic equation would feature a soluble silver salt, say silver nitrate...

`AgNO_3(aq) +NaI(aq) rarr AgI(s)+NaNO_3(aq)`

Silver iodide is as soluble as a brick, and precipitates from solution with alacrity.
