Introduction: Heartburn is a form of indigestion by acid digestion it affects many people worldwide. A solution to defeat heartburn is to take an antacid. An antacid is medicine which neutralizes your stomach acidity. In this experiment, we will be using three liquid antacids which are Phillips Milk of Magnesia, Life Brand Milk of Magnesia and Diovol plus AF and determine which one is the most effective at neutralizing an acid.
Purpose/problem:
The purpose of this lab was to test Diovol plus AF, Life Brand Milk of Magnesia, Phillips Milk of Magnesia and determine which antacid is the most effective at neutralizing an acid.
Hypothesis:
In my opinion, Diovol …show more content…
Transferred 5 drops from one of the 3 antacids and dropped them in the beaker with an eye dropper.
• 2. Before mixing, used universal pH paper to test initial pH value of the antacid and recorded results.
• 3. Dropped a single drop of phenolphthalein in beaker and mixed with stirring rod.
• 4. Started adding HCL acid to mixture, mixing with stirring rod every 5 drops.
• 5. Stopped when the mixture had returned to original state
• 6. Dumped mixture into waste beaker and cleaned up the area.
• 7. Repeated steps from 1-6 for all 3 liquid antacids.
Observations (Results): Antacid Neutralization titration results
Antacid Brand # of drops of antacid Initial pH paper color and pH reading # of drops of HCL added to change indicator Final pH paper color and pH reading
Life brand milk 5 Brownish, Green=12pH 104 Greenish yellow, = 7 pH
Phillips milk 5 Brownish, Green= 9pH 112 Light Orange = 6pH
Diovol plus AF 5 Light Green = 8pH 5 Greenish, yellow= 6/7pH
Analysis:
The milk was a white liquid when I recorded results for initial pH paper color for life brand and Phillips milk I got the color Brownish, Green.
Sources of errors: Sometimes my group and I put drops too fast and lost count. We could improve by being patient next …show more content…
Based on my results the most effective antacid was Phillips, milk of magnesia because the number of drops added was 112 drops. Which is the highest and having the most drops is a good thing because it proves that it is a very strong base, so when this base is used it would be the most effective to fight acid. The active ingredient in the acid is Magnesium Hydroxide. The chemical formula is Mg (OH) 2 + 2HCl = MgCl2 +
