Students will be able to explain that mixing substances can cause a chemical reaction that results in the formation of a new substance. Students will be able to plan and carry out an investigation to ...

Chemical precipitation is an effective treatment process for the removal of many contaminants. Coagulation with alum, ferric sulfate, or ferrous sulfate and lime softening both involve chemical ...

Since a precipitate is a solid it can be collected by filtering. The precipitate is left behind on the filter paper as residue which can be washed by pouring water over it when it is still in the ...

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 ...

There are many techniques to separate metal ions from a salt solution. Chemical co-precipitation is the most popular technique that is used in industrial applications because of its cheap raw ...

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 ...
