Question

You have three beakers.

Beaker 1: lithium carbonate
Beaker 2: strontium sulfide
Beaker 3: magnesium sulfate
You add a solution of sodium nitrate to each of the beakers and wait for a double displacement reaction to occur. Which beakers have precipitates (SELECT ALL THAT APPLY)

Beaker 1
Beaker 2
Beaker 3
All of the beakers
None of the beakers

Answer 1

There is no double displacement reaction in any of the beakers. Beaker 2 has a ppt of SrS which was in the beaker initially. It doesn't dissolve in NaNO3 solution.
