3. On the prelab you identified CaCO3, Na2CO3, and NaHCO3 as the three compounds that produce bubbles of gas when vinegar is added. When these three compounds come in contact with vinegar, they react with the acid in the vinegar and decomposes to form a gas. The gas is visible as bubbles traveling to the surface of the liquid. What gas is being formed? If you're not sure, ask the instructor for help. 4. When KOH (potassium hydroxide) is mixed with phenolphthalein, a bright pink color can be observed. What can you conclude about KOH?
