There are no calculations.
Analysis/ Critical Thinking Questions:
Compare your data for the pure substances with the data for each of the two solid mixtures. Which of the pure substances shows behavior that is similar to what you saw with the the two-solid mixtures (Mixture 1 and Mixture 2)? If you cannot positively identify your mixture, discuss the possibilities for the mixture. The starch and mixture 2 are both similar because they both did not penetrate when the vinegar was added; when the water was added the laid on top and did not penetrate completely; when the iodine solution was added to both they it turned black. Mix 1 would be substances 2 and 4; Mix 2 would be 1 and 5.

Mixture 1 is baking soda and starch; Mixture 2 is sugar and salt.
What is the major component of the unknown (Mixture 3), commonly used as an upset stomach and pain reliever? Compare your results to the ingredients on the package. Baking soda is the major component of the unknown mixture, which is commonly used as an upset stomach and pain reliever.
Two of the pure substances (baking powder and baking soda) are used to make baked products. What chemical property makes these substances useful in baking? How is this property useful in baking Which two of the five pure substances exhibit this property? Both substances release gas when combined with vinegar. This gas helps baked goods to “rise”.
Baking soda reacts with acidic solutions, but not with water. Identify which of the five pure compounds is baking soda, and which is baking powder. Explain. Number 2 is baking soda and number 3 is baking powder. Baking soda did not react with water and baking powder did.
One of our pure substances produced a characteristic color (blue-back) when it reacted with the iodine-alcohol solution. Starch is an organic compound you have probably encountered in your biology course. Identify which of the pure substances is
