​Mixing two soluble salts together

• ​ When two salts - potassium iodide and lead nitrate are reacted together they form two new substances -

• ​potassium iodide + lead nitrate → potassium nitrate + lead iodide

• 2KI(aq) + Pb(NO₃)₂(aq) → 2KNO₃(aq) + PbI₂(s)

​Making precipitates

​Sometimes one salt produced is insoluble in solution - so forms a precipitate in the mixture. Use the picture to answer the next slides

Poll

• No precipitate forms

• Yes a precipitate of sodium nitrate forms

• Yes a precipitate of silver chloride forms

Poll

Potassium sulfate solution is mixed with barium chloride solution. Predict whether a precipitate forms, and name any precipitate.

• No precipitate forms

• Yes a precipitate of barium sulfate forms

• Yes a precipitate of potassium chloride forms
