Question

Based on your observations and hypothesis, you can now determine which of the Solutions A, B, C and D in Step 3 might be the same as Unknown Solution I and Unknown Solution II. Select the answer below that accurately summarizes the statements you can now make about the two Unknown solutions.

Select one or more:

Unknown Solution 1 turned yellow. Therefore, this solution could be the same as Solutions A or D which also turned yellow. Unknown Solution II turned blue. Therefore, this solution could be the same as Solutions B or C which also turned blue.

Unknown Solution 1 turned yellow. Therefore, this solution could be the same as Solutions B or C which also turned yellow. Unknown Solution II turned blue. Therefore, this solution could be the same as Solutions A or D which also turned blue.

Unknown Solution 1 turned blue. Therefore, this solution could be the same as Solutions A or D which also turned blue. Unknown Solution II turned yellow. Therefore, this solution could be the same as Solutions B or C which also turned yellow.

Unknown Solution 1 turned blue. Therefore, this solution could be the same as Solutions B or C which also turned blue. Unknown Solution II turned yellow. Therefore, this solution could be the same as Solutions A or D which also turned yellow.

STEP 2
You add three drops of Dye X to the clear liquids in each bottle and observe what happens.
Dye X
Unknown Solution I
After you observed what happened when Dye X was added to each liquid, what question did you ask
yourself?
Unknown Solution II
Water

STEP 3
You are then given 4 additional solutions. Each of them contain chemicals dissolved in water. The
chemical formula for the chemical in each solution is listed. (See the Chapter 2 PowerPoint for an
explanation of chemical formulas.) You add Dye X to each bottle, and observe what happens.
Solution B: NaOH
Dye X
Solution A: HCI
Carefully study the chemical formulas for each solution.
a) What do the chemicals that turned yellow have in common in their chemical formula?
b) What do the chemicals that turned blue have in common in their chemical formula?
c) In chemistry, what are the chemicals that turned yellow called?
d) In chemistry, what are the chemicals that turned blue called?
Solution C: Ca(OH)2
Solution D: H₂SO4

Expert Solution

Step 1

The solutions which give H⁺ions are known as acids and the solutions which give OH^-ions are known as bases.
