0.1 M CH_3COOH with 0.1 MNH_3. The relative conductivities of the solutions test

Question

0.1 M CH_3COOH with 0.1 MNH_3. The relative conductivities of the solutions tested are as follows. 0.1 M CH_3COOH/0.1 M NH_4 measured in parallel: ____ Mixture measured in parallel: ______ Do the reactants exist as molecules or Ions? ________ Does the conductivity change indicate the creation of more ions or a decrease in the number of ions? _______ The total ionic equation for the reaction is ______ The net ionic equation for the reaction is _______ Interpret any changes in the conductivity of the solutions before and after mixing, in accordance with the preceding equations: 0.1 M H_2 SO_4 with 0.1 M Ba(OH)_2. The relative conductivities of the solutions tested are as follows. 0.1 M H_2 SO_4: ___ 0.1 M Ba(OH)_2: Mixture: The total ionic equation for the reaction is ____ The net ionic equation for the reaction is ______ Interpret any changes in the conductivity of the solutions, before and after mixing, in accordance with the preceding equation:

Explanation / Answer

C. 0.1 M H2SO4 + 0.1 M Ba(OH)2

total ionic equation,

2H+(aq) + SO4^2-(aq) + Ba2+(aq) + 2OH-(aq) ---> Ba2+(aq) + SO4^2-(aq) + 2H2O(l)

net-ionic equation,

H+(aq) + OH-(aq) --> H2O(l)

the conductivity decreases after mixing the two solutionsa s we get H2O formed, which is a wek conductor and has fewer H+ and OH- free ions in solutiion.
