Place the three glasses on a liquid-safe surface. Fill each cup with vinegar- 1 cup of vinegar in the first glass, 1/2 cup of vinegar in the second glass, and 1/4 cup of vinegar in the third glass. Place one Tums tablet in each glass. If you would like, you could time the tablets and see which dissolves the fastest. When you are finished observing the glasses, pour out the contents and thouroughly rinse the glasses out. Dry them and put them back on the surface you are working on. Now replace the same amounts of vinegar in each glass as you did before. After doing this, add 1 cup of water to the first glass, 1 1/2 cups in the second glass, and 1 1/4 in the third. Stir the mixtures and then once again place one Tums tablet in each glass, timing them if you would like. When you are finished watching the tablets pour the mixtures down the sink and wash the glasses.

I think that the more vinegar there is, or the more concentrated the vinegar is, the faster the tablet will dissolve.

Materials

Procedure

In the first half of the experiment, the tablets dissolved at about the same rate, although less of the tablet dissolved in the lower quantities of vinegar. In the second half, however, the tablet in the glass with a cup of vinegar and a cup of water dissolved rapidly, whereas the glass with only one fourth of a cup of vinegar dissolved so slowly the bubble were hardly moving. Altogether my hypothesis was correct- the glass with the most concentrated amount of vinegar dissolved the tablet the fastest.
