🧪 Predicting Precipitates in Aqueous Solutions

What you’ll learn

1. Start with the ionsIdentify the dissolved ions and distinguish dissolving from a net reaction.Precipitation predictions begin with the particles present in solution.
2. Use solubility rulesApply general solubility patterns and exceptions to proposed products.The product, its ions, and the listed exceptions determine the predicted phase.
3. Write the equationConstruct neutral formulas, assign states, and balance with coefficients.Correct formulas come before coefficients, and states show what remains dissolved.
4. See the net changeSeparate soluble electrolytes, identify spectators, and write the net ionic result.Cancel unchanged ions to reveal the chemical event—or confirm that none remains.
