In a lab, silver nitrate, AgNO3, is dissolved in water until no solid is observed in the container. Then, a solution of sodium chloride, NaCl, is added to the container. When you combine these aqueous solutions, there is no noticeable change in temperature; however, a solid precipitates and there is a slight change of color.
Which statements about the lab experiment involving silver nitrate and a sodium chloride solution are true?
a. The color change of the solution indicates a chemical reaction occurred.
b. Formation of a solid indicates a chemical reaction occurred.
c. The initial disappearance of silver nitrate in water indicates a chemical reaction occurred.
d. The lack of temperature change indicates a chemical reaction didn't occur.
e. A chemical reaction did occur when the solutions were combined.
f. A chemical reaction occurred when silver nitrate was added to water.
