Alka-Seltzer Reaction Rates Lab
Alka-Seltzer Counteraction Reprimands Lab What are the irrelative factors the movables the counteraction reprimand of Alka-Seltzer? Matthew Arkfeld Leah Gilligan Jessie Abbott Period 4 June 2nd, 2008 Backreason Research: o The extrinsic of the illustration was to mention if irrelative factors assume the counteraction reprimand of Alka-Seltzer. Alka-Seltzer provides unyielding support to pungent indigestion, disestablish stomach, heartburn, headaches, substance aches and aversions. It is an antpungent and aversion support therapeutics conservationd by millions of consumer’s natural. It is sold at national pharmacies balance the opposed and supermarkets worldwide. The primordial Alka-Seltzer was fabricated in 1931, the erratic ingredients are: 325 mg of Aspirin, 1000mg of Citric Pungent and 1916mg of Sodium Bicarbonate, purposed to manage aversion and concurrently countervail increase stomach pungent. It is supposing in the create of abundant effervescent tablets, which are dismemberd in a glass of steep. As the tablets dismember, the sordid (bicarbonate) and the pungent (citric pungent) counteract vigorously surrendering carbon dioxide steam, which too produces abundance motion to suffer the erratic ingredients to dismember unwillingly. In our lab, our extrinsic was to examination if steep at irrelative regions, salt, and vinegar, would assume the counteraction reprimand of Alka Seltzer tablets. Ultimately we provision, that the magnitude of the tablet would referable subject. Therefore, we determined to examination Alka Seltzer meek into bit and ampley reason up as courteous-behaved-behaved as the usual tablet. Conjecture and Variables: o Conjecture: We love that pungent steep, and vinegar achieve assume the reprimand of the counteraction, ultimately, the magnitude of the tablet does referable subject. Independent Variables: region of steep (ice, extent, pungent), Magnitude of tablet (whole, fragments, interlarded), Discontinuance it is in (tap, vinegar, salt steep). o Dependent Variable: The reprimand of counteraction of Alka-Seltzer. Materials: o 3-quart magnitude quarrels, 3 Alka-seltzer tablets, ice steep, extent region steep, pungent steep, stopwatch, thermometer, vinegar, salt, tablespoon. Procedure: 1. Scourteous single of the quarrels a third of the fashion with ice. Put tap steep in it until it is half fashion ample. Let it succeed to a steady region. 2. Scourteous the cooperate quarrel half fashion industrious with extent region steep. . Scourteous the third quarrel half fashion with pungent tap steep (course tap on pungent restraint single tiny). 4. Conservation the thermometer to archives region restraint the three steeps. Archives in table. 5. Put an Alka-Seltzer tablet in each quarrel and conservation a stopwatch to archives how multifarious cooperates it assumes to dismember. Do referable excite or knead the tablet! Archives entire results. 6. Put entire the liquids down the parch and scrub extinguished quarrels throughouly with steep. 7. Scourteous the quarrels half fashion with extent region steep. 8. In the primeval quarrel, assign a entire Alka seltzer tablet. Archives the interval it assumes restraint it to ampley dismember. 9.
Repeat stride 9 with the Alka seltzer meek into 8-10 fragments. Archives the interval it assumes to dismember. 10. Repeat stride 9 with the Alka-Seltzer tablet ampley crushed into interlard. (Crush betwixt two fragments of article with a rest) Archives the interval it assumes restraint it to ampley dismember. 11. Scrub entire quarrels ampley and throughextinguished again. 12. Scourteous single quarrel half the fashion with extent region steep. Scourteous another quarrel single half ample with vinegar. Finally scourteous the ultimate quarrel half fashion with salt steep. (2 tablespoons, extent region). 13. Pour an Alka-Seltzer tablet in each quarrel and archives interval it assumes to ampley dismember. 4. Observe your results. Observations and Data: | |Steep Region |Interval to Dismember | |Ice Steep |1 quality f |155 cooperates | |Extent Region |74 qualitys f |47 cooperates | |Pungent Steep |110 qualitys f |24 cooperates | |Interval to Dismember | |Entire Alka-Seltzer |45 cooperates | |Meek into Fragments |40 cooperates | |Powdered |11 cooperates | |Interval to Dismember | |Tap Steep |46 cooperates | |Vinegar |68 cooperates | |Salt Steep |77 cooperates |
Data Analysis: o We observed that a entire fragment assumes further interval to dismember in steep than an Alka Seltzer ampley reason up. As courteous-behaved-behaved as, region changes the press of the counteraction in the dissolving rule. Finally, vinegar, and salt, sluggish down the counteraction interval betwixt the tablet and steep. Conclusion: o We discovered that it is best to assume Alka seltzer with pungent steep in arrange to dismember the tablet the quickest.
As region decreases, the aggregate of interval that th counteraction assumes increases. As courteous-behaved-behaved as, adding other components such as salt and vinegar sluggish down rather than press up the counteraction. Therefore that rection is best in steep at a exalted region. o Our conjecture was evil-doing in that, seltzer-seltzer in irrelative shapes affcts the counteraction rather than referable causing any dissent in it. Sources of Error: Region could own been unpremeditated, thermometer was meek, and tap steep at extent region was assumeed by enthusiasm conditioning. Application: o Through this illustration we own skilled that region assumes the counteraction reprimand of Alka-Seltzer tablets. As courteous-behaved-behaved as, magnitude and discontinuance dismemberd in, can either press up or sluggish down the counteraction. Restraint unyieldingest results, Alka-Seltzer should be meek up into powered fragments and be assumen with pungent steep.
