Which is an example of a precipitation reaction?

a.
solid c6h12o6 combines with o2 gas to produce co2 gas and h2o gas.

b.
a solution of hcl mixes with a solution of naoh to produce a solution of nacl.

c.
a solution of agno3 mixes with a solution of nacl to produce solid agcl and a solution of nano3.

d.
solid fe combines with o2 gas to produce solid fe2o3.

Answer;

C. A solution of AgNO3 mixes with a solution of NaCl to produce solid AgCl and a solution of NaNO3.

Explanation;

-Precipitation reactions occur when cations and anions in aqueous solution combine to form an insoluble ionic solid called a precipitate. Whether or not such a reaction occurs can be determined by using the solubility rules for common ionic solids.

-Precipitates are insoluble ionic solid products of a reaction, formed when certain cations and anions combine in an aqueous solution.

-A common example is that of the mixing of two clear solutions: silver nitrate (AgNO3) and sodium chloride (NaCl): The reaction is;

                          AgNO3 + NaCl = AgCl + NaNO3  

- The precipitate forms because the solid (AgCl) is insoluble in water. That is true for all precipitates - the solids are insoluble in aqueous solutions.

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
