Naming precipitates
|
|
A precipitate is an insoluble solid product formed from the mixing of two solutions. Consider the reaction shown on the right. A white insoluble solid (precipitate) is formed when lead nitrate is mixed with sodium carbonate.

Now let's say we mixed two clear solutions of silver nitrate and sodium carbonate. How do we predict the name of the precipitate? Follow the steps listed below and shown in the animation on the right. Step 1 Write the names of each solution |
