Hypothesis:I believe that Tum will neutralize more acid because it is advertised more. If a company can spend that much time and money on advertising, then they most likely have a product they can stand by.

Materials: Two beakers

Burette

Two Mortars and pestles

Methyl Orange

One Tums tablet (uncolored and unflavored; this is important because if it is colored, the color mixed with methyl orange will affect the results

One Hy-Vee brand acid reducer(uncolored/unflavored)

Graduated Cylinder

Vinegar

Stirring Rod

Procedure: First, I crushed up one tablet of Hy-Vee brand acid neutralizer and one tablet of Tums brand acid neutralizer, using two mortars and pestels. Using a graduated cylinder, I filled two beakers with 50 mL of distilled water and labeled one "Tums" and one "Hy-Vee". After that, I added the tablets into their respective beakers. Using a stirring rod, I mixed the two solutions until all of the acid neutralizer was dissolved.

Then, I added 15 mL of methyl orange to each, again using a graduated cylinder, to the beakers. Nest, I filled a burette up to the "0" mark with vinegar. Having done this, I preformed a titration. I let the burette drip into the "Hy-vee" beaker until there was a color change in the beaker. I recorded my results and filled the burette bacvk up until it read "0", again. I then let the burette drip into the "Tums" beaker. After is changed colors, I recorded my results.

Results: According to my results, Tums neutralized 5.6 mL of vinegar (representing the acid), while Hy-Vee neutralized 2.3 mL of vinegar.

Conclusion: My hypothesis was right. Tums does dissolve more acid than Hy-Vee brand does.
