A hypothesis is a plausible explanation for a particular fact, observation, or process. Write a hypothesis about how the various concentrations of acid will affect the amount of limestone that is dissolved from each jar. You’ll need these materials for each group:
limestone chips (50 g total)
scale with at least 0.1 g accuracy
4 small plastic jars (may use clear, clean glass baby food jars)
graduated cylinder, 100 or 250 mL
safety goggles
disposable gloves
4 sticky notes or small pieces of paper and tape
white vinegar (at least 100 mL)
baking soda to neutralize the vinegar before disposal
distilled water (at least 100 mL)
small spoon that is long enough to scoop the limestone chips from the bottom of the jars
2 soft rags on which to spread all the limestone chips
pen, pencil, or fine-tip marker

I can only find a few of these materials. If you have done this experiment, please help me!!
