Do a demonstration to introduce the concept of a precipitate – formation of a solid from the reaction of two liquids. Remind students that they have seen that mixing certain substances can result in a ...

Below is an example of a precipitation reaction. Notice the two aqueous solutions make a solid substance. \(AgNO_{3}(aq) + NaCl(aq)\rightarrow AgCl(s) + NaNO_{3}(aq)\) If state symbols are not ...

Scoop a small amount of KI into the water directly opposite the Pb(NO3)2 A precipitate of PbI2 will form near the center of the dish.

The rate can be measured by placing the reaction container on top of a black ... can no longer see the X due to the formation of the precipitate, you can calculate the rate using the equation.

Aliphatic aldehydes and reducing sugars will form a yellow-to-red precipitate with Benedict's reagent, causing the blue solution to appear green-to-red. This reaction can be used as a test for such ...
