Acid-base titrations: analysis of antacid tablets essay

Use the calculated molarity from the volume of titrant to standardize the solution produced and prepare second half of experiment.

These components neutralize the excess stomach acids. You may feel a burning sensation during acid reflux. The higher the amount of HCl that can be neutralized by one gram of the tablet, the more efficient is the antacid tablet.

After that, the two drops of phenolphthalein indicator were added and was mixed thoroughly. Therefore, without adding a phenolphthalein indicator, there would be no physical change occurs so that means that it is almost impossible to indicate whether the hydrochloric acid has already been neutralized by the sodium chloride.

Antacids are attached to sodium, calcium, magnesium, or aluminum. Standardization of NaOH Trial 1. Antacids, like all medications, are attached to a base.

Lastly, the antacid mixture was titrated with 0. Titration involves determining the amount or concentration of an unknown substance, in this case stomach acids and antacids. This will become apparent when the solution remains a constant pink color.

Tums are calcium-based antacids, which can cause kidney stones to form. In the first trial, the weight of the tablet was 0.

Acid-Base Titrations: Analysis of Antacid Tablets Essay Sample

It is necessary to dissolve the antacid as completely as possible in the 0. Antacids increase the pH of the stomach almost immediately to relieve acid indigestion, heartburn, gastritis, and gastroesophageal reflux disease GERD.

The one that is fully neutralized of unknown concentration. Antacids relieve discomfort from heartburn by neutralizing stomach acid. Rollaids are aluminum-based antacids, which can cause constipation. Antacids are designed to raise the pH level of the stomach from a too-acidic state.

Get Access Acid-Base Titrations: Once cooled, add the indicator Methyl Purple. Then, the antacid was dissolved in the acid. September 29, More essays like this: In determining the efficiency of an antacid tablet, the volume of unreacted HCl in the antacid mixture is titrated with NaOH.

In this experiment, the reagents combined are an acid, HCl aq and a base, NaOH aq where the acid is the analyte and the base is the titrant. Excessive hydrochloric acid in the stomach causes a feeling of discomfort and a burning sensation beneath the breastbone resulting from a spastic backflow of this acid content into the esophagus.

Acid reflux is stomach acid coming back up to the throat through the esophagus. When the molarity of the solutions was computed, the result was 0.

Cengage Learning Asia Pte Ltd. Release the titrant into the analyte solution until the reaction has occurred completely. That means that we made a solution neutral. Data Summary Part A: Neutral pH is 7, while the normal stomach acid level usually is 2 to 4.The results for this experiment have shown up to be: the crushed tablets generally dissolve faster, rather than the whole tablets.

Introduction The antacid tablet, both crushed and whole, started off as a solid state. And both after a minimum of 18 seconds dissolved, and became one with the water, making it a liquid. Acid-Base Titrations: Analysis of Antacid Tablets Essay Sample. This experiment was performed to learn the technique of acid-base titration and to compare the efficiency of commercially available antacids by looking at their weight of HCl and weight of antacid values.

The analysis of antacid tablets was highlighted in this experiment. Acid Base Titration – End Point Indicators.
