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 ...

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 ...
