Question

In a lab. silver nitrate, AgNO_3, 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 properties and there is a slight change of color. Which statements about the lab experiment involving silver nitrate and a sodium chloride solution are true?

Answer 1

In this experiment aqueous solution of A^NO,, and N2C1 reacts to form a solid white precipitate of AgCl. The reaction involved in the given experiment is: AGNO, (aq)NaCl(aq)AgC1 (s)+NANO, (ag) Statement 1 The lack of temperature change indicates a chemical reaction didn't occur. This statement is false because the lack of temperature change is not a significant change to determine whether a reaction take place or not Statement 2 A chemical reaction occurred when silver nitrate was added to water is false because the S silver nitrate forms an aqueous solution which is a physical process Statement 3 The initial disappearance of silver nitrate in water indicates a chemical reaction occurred is false because the silver nitrate forms an aqueous solution which is a physical process Statement 4 The color change of the solution indicates a chemical reaction occurred is true because the silver nitrate and sodium chloride reacts to form sodium nitrate and solid white precipitate of silver chloride Statement 5 Formation of solid indicates a chemical reaction occurred is true because the silver nitrate and sodium chloride reacts to form sodium nitrate and solid white precipitate of silver chloride Statement 6 A chemical reaction did occur when the solutions were combined is true because the silver nitrate and sodium chloride reacts to form sodium nitrate and solid white precipitate of silver chloride.
