Question

1. What was your hypothesis? 2. Plot your data as drops of ascorbic acid vs. time. 3. As the concentration of ascorbic acid was increased, did the rate of the formation of the lodine starch complex Increase or decrease? Explain your answer in terms of the chemical reactions involved. 4. Was your hypothesis correct? 5. Make a general rule about the effects of concentration of reactants on reaction rates 6. For practice, the molecular formula for ascorbic acid is C6H806, and you used 6 g in this experiment, calculate the molarity of the ascorbic acid. Now calculate the concentration in moles per drop (assume 1 mL = 20 drops).​

Answer 1

1. I hypothesize that if you continue to add more drops, then the time it takes will continue to increase.

2. A; 9.70 secs, B; 14.63 secs, C; 18.78 secs, D; 28.70 secs, E; 31.45 secs.

3. The formation continued to increased. As more was added, the time it took to reach the full reaction was increased.

4. Yes.

5. When the concentration of all the reactants increases, more molecules or ions interact to form new compounds, and the rate of reaction increases. When the concentration of a reactant decreases, there are fewer of that molecule or ion present, and the rate of reaction decreases.

6. 6mL.

Step-by-step explanation:

1. for number one remember that the hypothesis doesnt have to be long or right, so you can basically put what you like if you truly dont know. but in this experiment they are asking you what you think will happen to the length of time.
2. for number 2, i measured the time of when each reaction turned black.
3. in the video, as more of the drops were added it took longer for it to turn black,, which is why i worded my answer that way. they are just asking did the time increase as you added more except this time they want the correct answer.
4. in this case my hypothesis was correct,, but you can change your hypothesis and put no for 4 if it makes you feel better.
5. i honestly looked this one up.
6. 6 is correct but i hope this helps.
