Experiment 8. Based upon the conductivities of the three mixtures prepared, relative to the conductivities of the reactants, determine whether or not a chemical reaction occurred, as follows: (a) Copy the relevant conductivity values from your data sheet and complete the table below: Conductivities (S/cm) Measured First Reactant Second Reactant Average of the Reactants NaCl KNO₂ Mixture I 4000 CaCl₂ Na CO₂ Mixture II HCI NaOH Mixture III (b) By comparing the average and measured conductivities, decide whether or not a reaction occurred in each mixture (see the background section of the experiment on the conductivity of mixtures, if necessary). If a reaction occurred, complete and balance the reaction equation below [including the appropriate phase (aq). (1), or (s) for each product]. Write N.R. if no reaction occurred. [For examples, see reactions (11)-(12) of the background section.] Hint: if needed, the solubility guidelines (given in section 4.5 of your lecture textbook) can help you determine the identity of the precipitate (solid) that formed in one of the reactions. 1. NaCl(aq) + KNO:(aq)→→→→→→→ II. CaCl₂(aq) + Na2CO3(aq) →→→ !II. HCl(aq) + NaOH(aq) →→→
