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.

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 ...

Chemical gardens are fascinating structures that form through precipitation reactions, where soluble ions react to create insoluble compounds that grow into intricate shapes. These processes are ...

A simple demonstration of how a precipitate is evidence of a chemical reaction taking place is performed by mixing solutions of calcium chloride and sodium carbonate to form the precipitate calcium ...

Scientists at Osaka University have designed a nanogate that opens and closes using electrical signals, offering precise ...

Can be used to recap on precipitation reactions or could lead into a classroom discussion on chemistry in society.
