Lab report Purpose to compare three types of vinegar by comparing the amount of ethanoic acid in them. Hypothesis: if the vinegar has more acid it will be conductive then the other once Explanation: The electrical-conductivity of a vinegar is a measure of how easily it lets an electric current flow. water is not a good conductor of electricity. Some substances when they are dissolved in water to make a solution it become a better conductor. Vinegar is an acid which is dissolved in water. All of the vinegar has ethanoic acid but some vinegar have more vinegar then the other ones. When ethanoic acid is dissolved in water it will produces ions and more ions added in the solution the vinegar will be more conductor because these ions carry the current through the solution. This is because acids contain hydrogen ions. Independent Variable: vinegar (La…show more content…
Dependent Variable: conductivity Controlled Variables: 1 same amount of vinegar 2 making the same number of tries Fair test: I will mesuare Materials: • Senso meter • biker 500cm3 volume bottle of La Talarette: • 500cm3 volume bottle of Haniavig: • 500cm3 volume bottle of Nicholayig • • • Procedure: 1) Gather all materials 2) Turn on the senso meter 3) Put the sensor of senso meter in Haniavig and redo again this step three times (make sure to wash the sensor after each try) 4) take average of the results Put the sensor of senso meter in Talarette and redo again this step three times (make sure to wash the sensor after each try) 5) take average of the results 6) Put the sensor of senso meter in Nicholayig and redo again this step three times (make sure to wash the sensor after each try) 7) take average of the results processing data: Haniavig: (0.17+0.17+0.16)/3= 0.16 Talarette: (0.15+0.14+0.14)/3=0.14 Nicholayig: (0.12+0.11+0.11)/3=0.11 vinegar conductivity haniavig 0.16 talaretta 0.14 nicolayig 0.11 Title: variability of conductivity among vinegar
