Is this a good lap report? Please fill in the blanks, please do as I ask , thank you
This lab assignment will be submitted for a grade. I have enhanced the Lab Report document found in the lesson and made it a little more user friendly for you here. You can submit either document, as they are the same questions. However, you will only be allowed ONE SUBMISSION. Blank files will be given a zero, so title and save your documents correctly and upload carefully. Be sure you don't leave questions blank or submit your file for grading if there is something you do not understand. There is a recording of this lab to help you if you have any questions, or come see me in Help Lab!
1.Introduction
- **Purpose**
The purpose of this experiment is to investigate how the concentration of hydrochloric acid affects the rate of reaction with magnesium ribbon. This study is important because understanding reaction rates is crucial in fields such as chemical engineering and pharmaceuticals, where control over reaction speed is necessary.
- **Background Information**:
Reaction rates can be influenced by various factors, including the concentration of reactants. According to the collision theory, an increase in the concentration of reactants typically leads to an increased rate of reaction as there are more particles available to collide. The chemical equation for the reaction is:
Mg (s) + 2 HCl (aq) → MgCh (aq) + H2 (g)
- **Hypothesis**:
If the concentration of hydrochloric acid is increased, then the rate of reaction will increase because there will be more HCl molecules available to collide with the surface of the magnesium ribbon.
### 2. Experimental Methods
**Materials**:
Hydrochloric acid (HCI) in varying concentrations (0.5 M, 1.0 M, 1.5 M, 2.0 M)
Magnesium ribbon
Stopwatch
100 mL beakers
Graduated cylinder
Ruler
**Procedure**
Cut four 2 cm strips of magnesium ribbon using a ruler and scissors for precise measurement.
Measure out 50 mL of 0.5 M hydrochloric acid using a graduated cylinder and pour it into a 100 mL beaker.
Submerge one strip of magnesium ribbon in the acid, and start the stopwatch immediately.
Record the time taken for the magnesium to completely dissolve and the effervescence to stop
Repeat steps 2-4 for 1.0 M, 1.5 M, and 2.0 M concentrations of hydrochloric acid.
Ensure all safety equipment, such as goggles and gloves, are used throughout the experiment.
### 3. Data and Observations
- **Data**:
Concentration of HCI (M)
Time for Mg to dissolve (s)
0.5
120
1.0
60
1.5
30
2.0
15
- **Observations**:
As the concentration of HCl increased, the reaction was noticeably faster. Higher concentrations resulted in more vigorous bubbling indicating the rapid production of hydrogen gas. This suggests a higher rate of reaction due to increased collisions between HCl molecules and the magnesium surface.
### 4. Conclusion
- **Summary**
The experiment confirmed that increasing the concentration of hydrochloric acid results in a faster reaction with magnesium. This was evident from the decreased time required for the magnesium to dissolve as the concentration of HCl was increased.
- **Discuss Results**:
The data supports the hypothesis, showing that higher reactant concentration increases reaction rate. This aligns with the collision theory, as more concentrated solutions provide more molecules to collide and react.
- **Analysis**:
Possible sources of error include timing inaccuracies due to human reaction time and variation in magnesium ribbon surface area due to handling. Additionally, measurements of acid concentration may not have been perfectly accurate. Improvements could involve using a more precise timing method, such as a computerized sensor, and ensuring consistent surface area of magnesium strips by using a machine cutter.
This should provide a comprehensive example of how you might fill in a lab report in a typical format. If you have specific data from your own experiments, you can substitute it into this template for a complete report.
