ProcedureGet two differents brands of antacid tablets from your T.A. For each one gather thefollowing informations about it such as the name of the tablet, the cost per bottle, thenumber of tablets in the bottle, the mass of the tablet, the component of the tablet asdescribed on the label. First, weight the first tablet by using the balance and then recordit. After this grind the tablets with the a mortar and pestle to make it a powder. Take about0.2 g from the powder by using the scoopula . Put this powder in 125 ml flask. ( note thatif the tablets are small you should take about 0.1 g). Pipette 25.0 ml of standardized ~ 0.1M HCl into the flask that contain the powder and swirl to dissolve it. Record the actualconcentration of HCl solution. Put the flask on hotplate, heat it about one minute toremove Co2. Remove the flask ( before the flask is hot) and then add 6 drops of tehindicator, bromophenol blue. Swirl the flask, if the turns blue, so that mean there is notenough HCl was added. If this happen, you can pipette an 10 ml of HCl and add it to theflask and heat it again. Record the concentration of HCl add to the flask. Obtain 50 ml ofNaOH solution in graduated cylinder. Record the concentration of NaOH. Use the funnelto fill the burette. ( make sure that there is no air bubbles in the burette tip). Recode theinitial volume of NaOH into 2 decimal places. Make sure that the flask that contain theantacid is cooled down before proceeding. Slowly start to titrate the solution of NaOHsolution until its turn faint blue endpoint. As the yellow colour start to disappear, slowdown that rate of delivery of NaOH to a dropwise flow. When a single drop results in theformation of teh blue colour, stop the delivery of NaOH. Swirl the flask and wait about10-15 seconds, if the colour does not change leave it, if does, add more drops of NaOHand repeat. Record the final concentration of NaOH solution in the burette. Do the samesteps to other 3 antacids tablet. After you finish, clean your work station. Put each on inthe waste chamber. If you are the last lab section, you need to drain any remaining ofNaOH in the burette and put it into the sink with running tap water. Rinse teh burettetwice with tap water, dispending through the burette tip, followed by twic with distilledwater. Clamp the burette upside down with tip open. Rinse each volumetric pipette twicwith tap water and twic with distilled water and clamp them upside down. If you are notthe last section of the lab in this day , leave the remain of NaOH to next student’s section.calcuation1) n= M * vv= 25 ml * 1L / 1000 ml= 0.025 Ln= 0.1003 mol/l * 0.025 L = 0.0025075 molThe number of mol is 0.002508 mol HCl2) Alka-seltzern= M * VV= 21.5 ml convert to L = 0.0215 LM = 0.1002 mol/ln= 0.0215 L * 0.1002 mol/ln= 0.002154 molmolar ratio of NaOH is 1:1therefore 0.002154 moles of HCl will remain unreacted from anatacid.0.002508 mol – 0.002154 mol = 0.000354 mol used of HCl to neutrlize the antiacid .TumsMoles of NaOH = 0.0148 L * 0.1003M = 0.00148 moltherefore 0.00148 mol of HCl remain from reaction with antacid.Initial moles of HCl 0.02508 mol0.02508-0.00148=0.0236 mol of HCl used for neutralization of antacid.3) Alka- SeltzerMole ratio of HCl base from the antiacid is 1:1HCl : NaHCO3 is 1:1Number of moles of base in the antacid powder is 0.000354 mol0.000354 mol NaHCO3 have 84.007 mol/ gMass= molar mass * amountMass= 0.000354 mol * 84.007 mol/gMass= 0.02974 g NaHCO3TumsCaCo3(s) +2H+ (aq) —> CA2+ (aq) + Co2 (g) +H2o (l)So, mole ratio of HCl : CaCO3 is 2:10.0236 mol HCl * 1 mol CaCo3 / 2 mol HCl =0.0188 mol CaCO3Mass= molar mass * amountmolar mass of CaCo3= 100.09 mol /gMass= 0.0188 mol * 100.09 mol/gMass= 1.181 g CaCO3second part1.1916g present in 3.5346gPercent of NaHCo3 = 1.916 g/ 3.5346 g *%100 = 54 %take 0.2002 g and 0.03g NaHCO3= 0.03 g/ 0.2002 g * %100 = 15 %So, it contains only 15% NaHCO3.Tums500 mg present in 1.5734 gconvert 500 mg to g = 0.5 gPercent of CaCO3= 0.5g /1.5734 g *100%= 32%take 0.2002 g and got 1.181 g=0.2002 g/1.181 g *100%=17 %So, it contains on 17 % CaCo3For Alka-selzer% Error= | Actual – experimental | / experimental * %100= | 15 – 54 | / 53 * 100 % = 72%So 72% error in number of grams of NaHCO3For tums% Error =| 17-32|/32*100%= 47%So 47% error in number of grams of CoCo34) cost of alka-seltzer = $3.99/24 = 0.167 centscost for one tablets = 0.167 cents1 tablets contains = 1.916 g NaHCO3n= 1.916 g / 84.007 mol/g = 0.023 mol0.023 mol = 0.167 cents1 mol = x0.023 mol x=0.167 centsx = 7.3 cents per molCost of Tums $5.29 /150= 0.03527 centsn= 0.5g /100.09 mol/g = 0.004996 mol0.004996 mol of CaCO3 = 0.03527 cents1 mol = x0.004996 mol x = 0.03527 centsx= 7.06 cents / mol5)
