Most Efficient Antacid Investigation Aim- To see which antacid tablet is the most efficient out of 4 samples. Plan- To do this experiment I will see how long it takes acid to neutralise each antacid tablet by titration. Neutralising a substance is when you find the point when it's neutral by using another substance with the opposite pH.
Repeat the titration procedure, above, 2 more times.. Stomach antacid tablets used in this experiment have been stored under laboratory conditions and may be contaminated. Do not taste any materials used in this experiment.. PART II: ANALYSIS OF STOMACH ANTACID TABLETS.
The Materials and reagents used in this experiment are the ff: For Reagents, standard 0.1 M HCI solution, standard 0.1 M HCI NaOH solution, 2 antacid tablets per brand and phenolphthalein indicator. For the materials, 250 ml Erlenmeyer flask, Base burette, Acid burette, medicine dropper, mortar and pestle, analytical balance and 100 ml graduated cylinder are used.
Antacid Tablet Analysis: An Experimental Approach to Acid-Base Titration Erin Votaw, Alioune Sakho, Matthew Wahhab, Alex Williamson, Richard Vela (Group 6) General Chemistry 102 (CHEM 102), ISP SCUHS February 12, 2015 Abstract: In this laboratory experiment, we sought to determine the active component of an antacid tablet.
Equilibrium and Acid-Base Chemistry. Neutralisation of Stomach Acid by Magnesium Hydroxide Antacid. Abstract: An experimental investigation was conducted to examine the chemical concepts of acid-base chemistry and equilibria in the form of a neutralisation reaction, with real world applications of indigestion in the human body.Using an antacid with the active ingredient of magnesium hydroxide.
They have sent five antacids to be tested with a back-titration that works as follows: First, each antacid tablet is mixed with 40 mL of 0.1 M HCl—this acidic solution is the same stuff that is in stomach acid, and one antacid pill is nowhere near enough to neutralize all 40 mL of the acid.
