Science

Experiment 1     Investigating the effects of temperature on reaction rates

Aim: I want to investigate hoe temperature effects the reaction rate.

Equipment:

• Conical Flask
• Beaker
• Measuring Cylinder
• Stopwatch
• Black cross on paper 
• Water Bath 
• Thermometer
• 0.1mol/L sodium thiosulfate 
• 1.0mol/L hydrochloric acid ( HCL ) 

Method: 

1. Put X on paper on the bench mat, and put the conical flask on top of paper 
2. Measure 50 ml of sodium thiosulfate solution and put it into beaker. 
3. Record the temperature of the sodium thiosulfate.
4. Measure 5 ml of HCL and pour this into the conical flask. 
5. Pour the thiosulfate into the conical flask start the stopwatch and swirl the flask, time how long it takes for the cross to disappear when viewed from above i.e look down from the mouth of the  conical flask.
6. Wash flask thoroughly.
7. Repeat the experiment using a water bath to heat the sodium thiosulfate to 30 degrees 40 degrees and 50 degrees keep the volume of acid the same each time. 

Results 

• room temp 28 seconds 
• 30 degrees 50 seconds 
• 40 degrees 19 seconds 
• 50 degrees 18 seconds 

Conclusion: A chemical reaction is when two reactants collide, they have to collide with enough force to and the correct orientation. As we made the temperature hotter it gave the reactants more kinetic energy so they moved faster. The faster the reactants move the higher chance of a successful reaction to occur in a lesser time. 

Experiment 2  Investigating the effect of concentration on reaction rate

Aim: I want to investigate hoe concentration effects the reaction rate.

Equipment: 

• A conical flask 
• measuring cylinder 
• stopwatch
• black cross on paper 
• 0.2mol/l sodium thiosulfate 
• 1.0mol/l of hydrochloric acid 

Method: Put the piece of paper with the X on the bench and put the conical flask on it.

1. Measure 10mL of Sodium Thiosulfate and put it into the conical flask.
2. Measure 40mL of Water and put it into the conical flask. Swirl to mix.
3. Measure 5mL of HCl.
4. Pour the Sodium Thiosulfate into the conical flask, start the timer and swirl the flask.
5. Stop timing when the you can't see the cross on the paper.
6. Wash out the flask thoroughly.
7. Repeat experiment 20mL of Sodium Thiosulfate and 30mL of Water.
8. Repeat experiment 30mL of Sodium Thiosulfate and 20mL of Water.
9. Repeat experiment 40mL of Sodium Thiosulfate and 10mL of Water.
10. Repeat experiment 50mL of Sodium Thiosulfate and no Water.

Results 

10ml of thiosulfate and 40ml of water took 3:22 seconds to react
20ml of thiosulfate and 30ml of water took 1:58 seconds to react
30ml of thiosulfate and 20ml of water took 0:57 seconds to react
40ml of thiosulfate and 10ml of water took 0:52 seconds to react

Conclusion: In conclusion the more thiosulfate you add and less water it is quicker to react and the more water and less thiosulfate you add it takes longer to react.


Experiment 3: Observing the effect of surface area on reaction rate

Aim: To make the simple observations during a reaction between calcium carbonate (CaCO3) chips powder with hydrochloric acid (HCL).

Equipment: 

• Boiling tube 
• Calcium Carbonate chips 
• Calcium Carbonate powder
• Hydrochloric Acid
• Measuring cylinder
• Spatula 

Method: 

1. Measure 2mL of hydrochloric acid and pour this int your boiling tube.
2. Holding your boiling tube over a sink or heatproof mat, add a pea-sized amount of Calcium Carbonate powder  to your boiling tube. Record your observation. 
3. Repeat the experiment but this time use a chip of calcium carbonate that is roughly the same size as the spatula of powder you used previously. Record your observation. 

Observation of Calcium Carbonate powder: When the powder reacted with the acid it fizzed up and small bubbles appeared at the top.  

Observation of Calcium Carbonate chip: When the chip hit the acid tiny bubbles came up from the bottom. 

Conclusion: 



Experiment 4  Observing the effect of a catalyst on a chemical reaction

Aim: To observe the effects of a copper catalyst on he reaction between zinc and sulfuric acid.

Equipment: 

• Three test tubes
• test tube rack 
• 10ml measuring cylinder 
• dropping pipette 
• granulated zinc
• copper turnings or powder 
• dilute sulfuric acid 

Method 

1. Add roughly the same mass of zinc in test tubes 1 and 3 
2. Add roughly the same mass of copper to test tube 2 and 3 
3. Add 5 ml of the acid to test tube 1 note the rate and production of gas bubbles
4. Add 5 ml of acid to the test tube 2 note the rate and production of gas bubbles 
5. Add 5 ml of the acid to test tube 3 not the rate of production of gas bubbles 

Test tube 1: When both products reacted it bubbled and went cloudy. 

Test tube 2: When both products reacted s few bubbles a pared and the powder went to the top and then the powder turned clear. 

Test tube 3: The products bubbled a lot and it separated. 

Catalyst: It speeds up a chemical reaction

Purpose of test tube 2: It was to show what would happen with only copper and the acid, it didn't react.

Sunset

Sunset- the day's final goodbye.The sky broke like an egg into full sunset as the lake caught fire. The glistening lake reflected the exquisite pinks, purples and tinges of orange that lined the sky. No cloud was in sight. It looked like something straight out of a painting. The hum of the young grey feathered birds was loud and the squealing giggles of small children made this place seem all too peaceful. Dogs ran around play fighting while wagging their tails in the air, huge grins spread across their faces. With the sunset fading and the tall buildings that were scattered around the city, what seemed like cold lifeless blocks of concrete, came to life and started to light up New York City. The light of  day was lost once again to the darkness.

Midnight  

As the clock struck 12 the only light source in the city came from the soulless dull concrete buildings, behind the now dark and mysterious lake. The hum of the birds stopped and no small children were in sight. This whistle of the old dying oak trees and swooshing of the brown crunchy leaves made it seem all too like a horror movie. The eerie darkness of the night never escapes your mind. The air was bitter with warmth nowhere in sight. The city was dark and silent. A pitch-black curtain draped over the sky as tiny stars scattered around it providing a sense of beauty in the darkness.

Sunrise

It was a brisk summer morning with a slight wind waving around the air. The air was crisp enough to send a slight shiver down your spine. Darkness had not long surrendered to the light. The sun rose out of the sky like a spirit rising out of a grave. The sky was ablaze with fiery reds, oranges and yellows. A light dew covered the fresh green grass surrounding the slightly fogged  lake. Sparrows chirped an explicit background melody. As the City started to awaken, the hum of the birds grew louder and the giggles of small children came back to life. The city was buzzing once again.

Victorian Freak Shows 

For centuries the word 'freak' has been used cruelly to describe people born with 'abnormal' features or those who are able to perform extraordinary physical acts by misshaping their bodies.
