My experiment was to have eight drops of liquid in each well. For a one I had five drops of Na2S2O3 and three drops of hydrochloric acid. For well A2 I had four drops of Na2S2O3, One drop of distilled water, and three drops of hydrochloric acid. For well a three I had three drops of Na2S2O3, two drops of distilled water, and three drops of hydrochloric acid.

1. Each well has 8 drops of liquid. Use the formula M,V, M₂V₂ to calculate the molarity
of the Na S,O, in each well. For more information about this formula, read the
Introduction in Lab 19: Titration. Record this data.
2. Plot the time, / (on the y-axis), against concentration, M (on the x-axis). Is the curve linear?
3. Assume the same amount of sulfur precipitated in each well to hide the Xs. The reaction
rate for each well is then precipitate/time. This is proportional to 1/t. Calculate and
record 1/t.
