Part 1. Calculate the Volume of One Drop of Solution Assume the density of water to be 1.00 g/mL. mass of 1 drop (g) 1L Volume of one drop = X 1.00 g/mL 1000 mL Part 2A. Calculate the Rate (The rate will be expressed as -A [BrO3-1/At). Step 1: Finding how many moles of thiosulfate you started with In each reaction there is one drop of 0.0010 M Na2S2O3 solution. Calculate the number of moles of S2032 present in one drop: 2 drop 0.010 M solution pniwollot od otni alleen or eine bns Ingm Step 2: Finding how many moles of bromated that reacted The blue color begins to appear when all the thiosulfate ion is consumed. Examination of reactions 1 and 2 allows us to calculate the moles of BrOy which react as all of the S2O32 ion is used up. 12 (aq) +2 S2O2 (aq) 21-(aq) + SO2 (aq) RXN 1 61-(aq) +BrO3-(aq) + 6 H+ (aq) 3 12 (aq) + Br- (aq) + 3 HO (1) RXN 2 Using dimensional analysis, calculate the amount of mol BrO reacted Step 3: Finding the change in concentration for the bromate ion 183 ment 12 men Data Table 2.
