Question

4. In this scenario, you are a chemistry professor and you want your students to perform a theoretical/percent yield precipitation reaction. The students will collect the precipitate and determine their percent yield. At the end of the experiment, all materials must be disposed of correctly and safely.

The procedure in the laboratory experiment manual calls for students to mix equal quantities of silver nitrate solution with sodium chloride solution. The safety warning stated in the experimental procedure is that silver salts are toxic.

a. Write a balanced chemical and net ionic equation for this reaction. Include all physical states (i.e. s, l, g, aq)

b. What type of chemical reaction is the precipitation classified under?

c. What is the chemical formula and name of the precipitate formed?

d. What is the produce that would be labeled "hazardous waste"?

e. Write a precipitation reaction for which the products would be considered more environmental friendly.

Explanation / Answer

a) balanced equation:

AgNO3 (aq) + NaCl (aq) ----------------------> AgCl (s) + NaNO3 (aq)

net ionic :

Ag+ (aq) + Cl- (aq) ------------------> AgCl (s)

b)

double displacement reaction

c)

precipitate formula is AgCl

its name : silver chloride

d)

NaNO3 is hazardous waste

e)

Ca+2 (aq) + CO3-2 (aq) -----------------> CaCO3 (s)

it is environmental friendly.
