Problem 71E

For each compound (all water soluble), would you expect the resulting aqueous solution to conduct electrical current?

a. CsCl                 b. CH3OH                 c. Ca(NO2)2                         d. C6H12O6

Step-by-Step Solution:
Step 1 of 3

Solution: Here, we are going to determine the concentration of each ion or molecules in the given set of compounds. Step1: a) NaNO , being an ionic compound will dissociate completely to give sodium and nitrate 3 ion as shown below: NaNO ----3---> Na + NO + 3- + - Here, 0.25 M NaNO will have 0.23 Na ions and 0.25 M NO ions in solution. 3 Step2: b) MgSO , being an ionic compound will dissociate completely to give magnesium and 4 sulfate ion as shown below: 2+ 2- MgSO ----4---> Mg + SO 4 -2 -2 2+ -2 2- Here, 1.3 x 10 M NaNO will have 1.3 x3 M Mg ions and 1.3 x 10 M SO 4 ions in solution. Step3: c) C 6 O12 b6ng a non-ionic compound will not dissociate into ions. Thus, 0.0150 M C H O will6av12.060 M C H O in solution. 6 12 6 Step4: d) Volume of NaCl solution before mixing(V ) = 45.0 mL = 45 / 1000 L = 0.045 L 1 Molarity of NaCl solution before mixing(M ) = 0.272 M 1 Volume of NaCl solution after mixing(V ) = 45.0 + 65.0 = 110.02L = 110/1000 L = 0.11 L Now, using the expression for dilution, we get, V 1M = V1 M 2 2 0.045 X 0.272 = 0.11 X M 2 M 20.01224 / 0.11 M 20.111 M Similarly, For (NH ) CO solution, 4 2 3 Volume of (NH ) CO so4 2n be3re mixing(V ) = 65.0 mL = 65 / 1000 L 10.065 L Molarity of (NH ) CO so4 2n b3ore mixing(M ) = 0.0247 M 1 Volume of (NH ) CO so4 2n af3r mixing(V ) = 45.0 + 65.0 = 110.0 2 = 110/1000 L = 0.11 L Now, using the expression for dilution, we get, V 1M = V 1M 2 2 0.065 X 0.0247 = 0.11 X M 2 M = 0.0016 / 0.11 2 M = 0.0145 M 2 Now, NaCl, being an ionic compound will dissociate completely to give sodium and chloride ions as shown below: + - NaCl ---------> Na + Cl + - Here, 0.111 M NaClwill have 0.111 Na ions and 0.111 M Cl ions in solution. Similarly, (NH ) CO , being an ionic compound will dissociate completely to give 4 2 3 ammonium and carbonate ion as shown below: (NH ) 4 2----3--> 2NH + CO 4 3- + Here, 0.0145 M (NH ) CO will hav4 2x 0.3 5 = 0.029) M NH ions and 0.0145 M 4 2- CO io3 in solution. ------------------
