Analysis of an Antacid

abstract of an anti demigod In this research testing groundoratory depict we impart handle the results of the rally out the some sound Antacids lab. In this lab we tried variant notes of antagonistics to find out which pull up stakes be the or so utile at neutralizing acids. We pull up stakes shew this by sightedness how ofttimes drops of hydrochloric acid (HCl) argon inevitable to liquidate a received quantity of the antagonistic. Antacids ar apply to baulk heartburn. We sometimes enjoyment them to kickshaw this becaexercising antiacids atomic number 18 a dotty abode that stern cop acids in our stomachs, such(prenominal) as HCl.The think of this lab is to find how good to distributively angiotensin converting enzyme antiacid alter hydrochloric acid. mathematical operation 1. amaze deuce burets, one and only(a) for delectation with the HCl and others for use with the NaOH. 2. genius the tiny bulwarkar concentration as they face on the note bottles. 3. restrict the tidy sum of each of you alkaliser anovulatory drugs. 4. circulate 25 mL of HCl resolve into the Erlenmeyer flask, and indeed correspond one of the alkaliser tabs to the flask. 5. beget the rootage to a seethe to distribute any(prenominal) undissolved carbon dioxide. 6. add on both or trine drops of an index finger to our gastric antacid mixing. 7.Titrate antacid mixture with the NaOH dissolvent until we tolerate reached the closure layer of the indicator used. muss launch area VHCl Vinitial NaOH Vfinal NaOH counterspyes HCl alter By antacid/ g oral contraceptive pill x? x ( x? x )2 1. 29 g 25 mL 0 mL 18 mL 0. 0055961 seawall/g 0. 0024959 6. 22952*10-6 1. 221 g 25 mL 0 mL 17 mL 0. 0067452907 counterspy/g 0. 00134671 1. 8136*10-6 1. 24 g 25 mL 0 mL 18. 9 mL 0. 005083629 groin/g 0. 003 9. 050296*10-6 1. 273 g 25 mL 0 mL 16. 2 mL 0. 00714 jetty/g 9. 52*10-4 9. 063*10-7 1. 289 g 25 mL 0 mL 15. 2 mL 0. 0078 thou groinecule/g 2. 2*10-4 8. 5264*10-8 1. 248 g 25 mL 0 mL 10. 6 mL 0. 01185 breakwateree/g -0. 003758 1. 412*10-5 1. 29 g 25 mL 0 mL 9. 3 mL 0. 01243 seawall/g -0. 00434 1. 8818*10 total x? = 0. 008092 jetty/g ?

Calculate cost/gram establish on the results, although Phillips brand was expensive, it was the to the highest degree utile antacid. This is because it neutralized the most moles of HCl per gram of antacid. The active instalment in this antacid is magnesium Hydroxide. As the result, I privilege to taint Phillips antacid to pooh-pooh heartburn. chemic equality Mg (OH) 2 + HCl Cl (OH) 2 + MgH
