Two Ions React; Two Never Move

You'll learnhow to strip a reaction down to the ions that actually changed, and which species must be left whole.

Pour silver nitrate into sodium chloride and a white solid drops out of a clear liquid. The equation you write names four compounds; the beaker holds twelve loose ions, and only two of the four kinds do anything at all. Twelve short steps; press Next for each one.

twelve loose ions · one white solid · two that never move
Before you start
What you're looking at
A beaker just after two clear solutions were poured together, with every ion drawn.
The question
Which of the four kinds of ion actually react, and which drift through untouched?
