How fast can you size up




















What reaction do you think is taking place? Once all the solid material of the tablet has dissolved in the water and the chemical reaction is completed, stop the stopwatch and write down the reaction time on a sheet of paper.

How long did the reaction take? Do you think this reaction is fast or slow? Get a fresh glass of water and this time take the antacid tablet that you broke in half.

Take both pieces of the tablet and hold them above the water surface. What do you think will change once you put the two pieces of the tablet into the water compared to the whole tablet?

Reset your stopwatch and get it ready. Drop both pieces of the tablet into the water and start the timer again.

Compared to the whole tablet, do you see the same reaction happening in the water? Again, stir the water gently and observe how the two tablet pieces dissolve in the water. Do you see more or fewer bubbles forming? Do you think this reaction will be complete faster or more slowly than with the whole tablet?

Once all the solid tablet material has completely disappeared and the bubbles have stopped forming, stop the stopwatch and record the reaction time.

Did the reaction time change compared to the whole tablet? Was this reaction faster or slower? Why do you think this is the case? With the two remaining glasses, repeat the antacid-adding steps with the antacid tablet that you broke into four pieces and the tablet that you crushed into a powder. Do you observe any changes in the chemical reaction happening in the water? How fast or slow are these tablets dissolving compared to the other tablets?

Do you notice any correlation between the reaction time and the size of the tablet pieces? Extra: Can you think of other chemical reactions that you could use to test how the surface area of one of the reactants affects the reaction rate with water?
