Neutralisation

Aim: To observe a neutralisation reaction.

Equipment: Test tube rack, test tube, 1 mol L-1 Na2CO3 (sodium carbonate), 1 mol L-1 HCI (hydrochloric acid), dropper or dropper bottle, universal indicator solution.

Method:

1. Add approximately 1-2 mL of NaCO and place the test tube into the test tube rack. Add 3-5 drops of Universal indicator solution.
2. Using a dropper bottle, add HCI drop by drop. Be extra careful because adding even a small amount of acid can mean you'll miss the neutralisation point.

Results:

Discussion:

As we were doing our experiment, our work succeeded and turned neutral, as we finished our neutralisation, we tried to mix some things altogether, as a result, we came up with a rainbow-like effect into a single Testube.

Making an Indicator

Aim: To make acid-base indicators using everyday substances.

Equipment:

• Red cabbage
• a Beaker
• Water
• Tripod

Method:

1. Chop the cabbage into small pieces until you have enough to fill 2 cups.
2. Place the cabbage in a large beaker and add water to cover the cabbage.
3. Boil over a bunsen burner for at least ten minutes for the colour to leach out of the cabbage.
4. Filter out the plant material to obtain a red-purple-bluish colour liquid. This liquid is at about pH7. ( The exact colour you get depends on the pH of the water.)
5. Place in a small beaker and leave to one side.

Results:

Discussion:

After we boiled the cabbage, Using a pipet we dropped a few cabbage indicator unto the spotting tile, we did the same thing with the other indicators like tea, cranberry, turmeric and beetroot. We then dropped a few HCI (acid) into some of the indicators. While on the rest we used NaOH(Alkali-base)

Conclusion:

We successfully made our indicators and came up with a result for each one.

SEXXY paragraph continuation

In English, we've been doing some SEXXY paragraph practice. Today, we're doing the continuation of our practice.

The Film aspect Two shot was used effectively to illustrate the scenes' principle, pride and fear. For

example, we can see this by distinguishing the lighting - low key, as well as the drastic difference in their facial expression. Avildsen did this to Portray the emotions of Geel Piet as Sergeant Borman Threatens him. This made the audience feel nerve-racking and worried about Geel Piet's Situation. This aspect can be contrasted to the scene where Sergeant Bormann had his batton on his side, it has a similar effect to the audience.

Power of one SEXXY paragraph

In English, we watch the film Power of One, after we watched it we've been practising our SEXXY paragraph for the past few days.




In the film Power of One, the aspect of long shot was used cleverly, to portray the scenes' essence which is fear. For instance, we see the baton of sergeant Bormann hanging on his side on the foreground while we see some prisoners, Geel Piet and Pk on the background. The director did this to emphasise the guard's power and what he could do to Geel Piet. This made the audience feel the suspense and the freight of both Geel piet and Pk. This aspect can be juxtaposed to the scene where it shows Maria's father's house. It shows the extreme difference between the slums and the mansion
