Conductivity distilled water 0 tap water 1 1 M HCl 264 0.1 M HCl 36 1 M NaOH 150 0.1 M NaOH 20 95% ethanol 0 1 M acetic acid 2 0.1 M acetic acid 1 1 M NaCl 76 0.1 M NaCl 11 0.01 M NaCl 2 sat'd BaSO 4 0 Purpose: To determine the equivalence point between an acidic and a basic solution during titration. Procedure : 1. The conductivities were measured for the following solutions: distilled water, tap water, 1 M HCl, 0.1 M HCl, 1 M NaOH, 0.1 M NaOH, 95% ethanol, 1 M acetic acid, 0.1 M acetic acid, 1 M NaCl, 0.1 M NaCl, and 0.01 M NaCl. 2. An unknown concentration of HCl was received from the stock room. 3. 10 mL of the unknown solution was then titrated with 0.0958 M NaOH. 4. The conductivity of the solution after each addition of 1-2 mL of NaOH was measured. 5. The titration of the unknown with 0.0958 M NaOH was then repeated. 6. 25 mL of 0.1 M acetic acid was titrated with 25 mL of 0.0958 M NaOH with the conductivity of the solution measured after every 1-2 mL addition of NaOH. 7.
