Question
Data Directions for completing the experiment: On the following tables, supply the information for each reaction you choose. Use the following terminology f your observations: (a) "Precipitate formed" (include the color. (b) "Gas evolved," (e)"Heat evolved," or (a) No reaction observed." Write correct formulas for the reactants and products, taking into account the charge numbers of the ions involved and make sure you use "g to indicate a gas and "s" to indicate a precipitate. Be In the case of a "redox reaction, indicate the oxidation number of each element in both the reactants and the products. In the case of an acid-base neu tralization reaction, label the acid and the bse in the reactants. Watch each reaction and record your own observations. Each person must write the reaction equations indi- vidually. Although you will work together to do the reactions, it is not acceptable to copy reaction equations from another student I.

DESIGN A REACTION THAT PRODUCES AN INSOLUBLE CHLORIDE A .-11: pr fb Reactants: Observation Molecular Equation: Complete lonic Equation: Net lonic Equation: ype of Reaction HM 210 Lab 7Explanation / Answer
I. forming insoluble hydroxide
Reaction : Fe(NO3)3(aq) + 3NaOH(aq)
Observation : red-brown precipitate Fe(OH)3
molecular equation : Fe(NO3)3(aq) + 3NaOH(aq) --> Fe(OH)3(s) + 3NaNO3(aq)
ionic : Fe3+(aq) + 3NO3-(aq) + 3Na+(aq) + 3OH-(aq) --> Fe(OH)3(s) + 3Na+(aq) + 3NO3-(aq)
net-ionic : Fe3+(aq) + 3OH-(aq) --> Fe(OH)3(s)
Type of reaction : precipitation

2. Insoluble chloride
Reaction : AgNO3 + NaCl
Obervation : white precipitate of AgCl
molecular : AgNO3(aq) + NaCl(aq) --> AgCl(s) + NaNO3(aq)
ionic : Ag+(aq) + NO3-(aq) + Na+(aq) + Cl-(aq) --> AgCl(s) + Na+(aq) + NO3-(aq)
net-ionic : Ag+(aq) + Cl-(aq) --> AgCl(s)
Type of reaction : Precipitation
