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 ...

Precipitation systems depend on the nature of a precipitation reaction, which results in the desired solid. Many solids precipitate or fall out of a solution when another component or chemical is ...

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 ...

When additional base is added, the precipitate dissolves. The reactions can then be reversed with the addition of hydrochloric acid. The precipitate will reappear and then redissolve. Turn on stir ...

Students investigate reactions which produce a gas, form a precipitate, and cause a color change. Students also explore endothermic and exothermic reactions and do an engineering activity to design a ...

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.
