Gumby and His Journey for Sugarlumps

The Sugarlump Story

Sugarlump opened November 2006 in the heart of San Francisco's sunny Mission District. Our spacious, inviting cafe was renovated from the ground up with many reclaimed and recycled materials. The Mid-Century eclectic interior is furnished with hand picked gems found on Craigslist and from Bay Area garage sales, as well as a few beautiful pieces crafted by local artists. Come see us - we think you'll feel right at home! Gumby decided to go on a quest to find the sugarlumps, he had a tough time finding them. On his journey he encountered grizzly bears, giant tuna and cavewomen. He had to overcome these perrils to find the sugarlumps.

- OIL RIG good pneumonic to remember oxidation and reduction.

- Reductant (reducing agent) becomes oxidised.

- Oxidant (oxidising agent) becomes reduced.

Solve problems and analyse information to calculate the potential Eø of named electrochemical processes using tables of standard potentials and half equations:

- More electronegative will displace more positive. E.g. iron will displace copper , but not magnesium from solution.

HSC Practical #1 - Reactions of Hydrocarbons With Bromine Water

Synopsis: In this experiment we tested the reactivity of different hydrocarbons. Our tests showed us that the -enes reacted with little energy whereas the -anes required UV. We tested each of the hydrocarbons with bromine and bromine water, if they didn't react in the lab we took them to the sunlight.

Aim: To test the reactivity of different hydrocarbons.

Available Chemicals/Materials: 1-hexene, hexane, cyclohexene, cyclohexane, toluene (C7H8), Bromine water, Bromine (to be administered by TB), micro test-tubes, UV lamp/The Sun!!

Method:

1. Select appropriate hydrocarbons to show the different reactions between saturated & unsaturated hydrocarbons with bromine & bromine water. Record the appropriate safety information from MSDS sheets.

2. Plan a suitable method - consider suitable quantities & safety precautions

3. Design an appropriate table to record your results.

4. Present a written report to summarize your findings, answering all discussion questions and appropriately labeling equations to prevent any mis-interpretation.

NOTE: Deposit all ORGANIC WASTE in the labeled container in the fume cupboard.

My Method:

. Put a small amount (1/2 pipette) of each hydrocarbon into a micro test tube.

. Add bromine water to each (1 or 2 drops).
