The change in color to yellow occurred only when all chemicals were mixed together

What happens if you mix a solid with water before adding the other solid?

What happens if you mix a solid with water before adding the other solid?

# data[].attributes.body
well when we mixed the baking soda in the water first the reaction was normal when we added the the second solid. when we did the same for CaCl2 it gave of a temp change before adding the baking soda

# data[].attributes.body
when cacl mixed with both liquids a temperature change occurred

What combination of substances make the temp change?

What combination of substances make the temp change?

# data[].attributes.body
Calcium chloride and either liquid make the temp increase.

The mixture of cacl2 and water when I mixed cacl2 with water It got warm

# data[].attributes.body
The Calcium Chloride mixed with the Phenol Red caused a reaction and the color changed to a yellow shade.

The pool stuff had unknown ingredients in it so we can assume the mixing of the phenol red with some unknown substance made it smell bad.

How much does the amount of the product affect the outcome?

How much does the amount of the product affect the outcome? 

# data[].attributes.body
Yes, although not as greatly as we thought. When the calcium chloride and sodium hydrogen carbonate levels increased the differences were minimal and the overall product was almost the same.

Sodium hydrogen carbonate makes it fizz

What would happen with different combinations of the 4 ingredients, is there one ingredient that makes the reaction the most effective?

What would happen with different combinations of the 4 ingredients, is there one ingredient that makes the reaction the most effective?

# data[].attributes.body
The CaCl2 was the most important ingredient to include because without it, there was no reaction, the ingredients just mixed together.

# data[].attributes.body
The color change that occurred to make it yellow was caused only by all the chemicals mixing.

Adding more baking soda decreased the reaction of the gases causing less inflation. There were some bubbles but not any gas and not much heat.

What if we add more phenol red to the experiment?

# data[].attributes.subject
What if we add more phenol red to the experiment?

# data[].attributes.body
The phenol Red causes the heat in the reaction. We did multiple tests taking away different substances but when we take the phenol red away there was no heat produced, therefor it must cause heating to occur
