Vitamin C is a vital nutrient for the human body. It plays a crucial role in the immune system, helps to absorb iron, and promotes healthy skin. Many people take vitamin C supplements to ensure they are getting enough of this nutrient.
The Experiment
In this experiment, a vitamin C tablet was dissolved in 50.0 ml of water. The purpose of the experiment was to determine the concentration of vitamin C in the tablet.
Materials
The following materials were used in the experiment:
Vitamin C tablet
50.0 ml of water
250 ml Erlenmeyer flask
Burette
0.01 M iodine solution
1% starch solution
Procedure
The following steps were taken to perform the experiment:
The vitamin C tablet was weighed and crushed into a fine powder.
The powder was added to the Erlenmeyer flask containing 50.0 ml of water.
The flask was swirled to dissolve the powder completely.
A burette was filled with 0.01 M iodine solution.
A small amount of the vitamin C solution was added to a test tube.
A few drops of 1% starch solution were added to the test tube.
The iodine solution was slowly added to the test tube until the solution turned blue.
The volume of iodine solution used was recorded.
Steps 5-8 were repeated until three consistent results were obtained.
Results
The average volume of iodine solution used was 25.0 ml. The concentration of vitamin C in the tablet was calculated to be 0.05 M.
Discussion
The experiment showed that the vitamin C tablet had a concentration of 0.05 M. This information is important for people who take vitamin C supplements and want to ensure they are getting enough of the nutrient.
Conclusion
In conclusion, the experiment demonstrated a simple method for determining the concentration of vitamin C in a tablet. This information can be useful for people who want to ensure they are getting enough of this important nutrient.
