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
