  2. Question: What combinations will react with each other?

  3. Hypothesis: Both the sodium bicarbonate and the calcium chloride will react with the bromothymol blue and we think that the sodium bicarbonate will be a base and the calcium chloride will be acidic.

  4. Variables: Independent Variable: the chemicals that are being combined. Dependent Variable: the reaction that occurs.

  5. Procedure: • Put 10mL of bromothymol blue in a test tube. • Measure .3 grams of sodium bicarbonate. • Pour the sodium bicarbonate into the test tube with the 10mL of bromothymol blue. • Mix substances carefully. • Record the data. • Repeat steps 1-5 using calcium chloride.

  6. Table:

  7. Summary: When we mixed the sodium bicarbonate with bromothymol blue the color stayed the same. The temperature went up .2°C. When we mixed the calcium chloride with the bromothymolblue the color changed from blue to light blue. The temperature went up 4.3°C.

  8. Graph: This graph shows how the temperature changes when certain chemical reactions occur.
