Neutralization.

Aim-
 To observe a neutralization reaction.

Method-
add appropriately 1-2 ml of na2 co3 and place the test tube into the test tube rack add 3-5 of universal indicator solution.

using a dropper bottler, add HCI drop by drop. Be careful because adding a small amount of extra acid mean you you'll miss the neutralization point. 

Result-


Dissuasion-
We first tested the indicator with the acid then it turned into red then. We used indicator with base then is started to make this blue purple colour. We keep on doing it until we got all the colour. we all had a part into to help, it was a success.

Conclusion-
This was the result that had pop out to be after the experiment but mainly having fun . WELL DONE GUYS.

Making Indicators

Aim-To make acid-base indicators using everyday substance.

Method:
Chop the cabbage int small pieces until you have enough to fill 2 cups. Place the cabbage in a large beaker and add water to cover the cabbage. Boil over a Bunsen burner for at least ten minutes for colours to leach out of the cabbages. Filter out the plant material to obtain a red-purple-bluish coloured liquid. This liquid is at about hp 7 [the exact colour you get depends on the ph of the water.
Places in a small beakers and leave to one side. repeat this method for beetroot.

Result


Discussion
My group had decide to experiment on acid and base for cabbage, the acid made the indicator red. Then the base made the indicator green. If you mix it together it made up different colours showing whether is basic or acidic.

Conclusion 
This is the after finishing and is was a success. By mixing the acid-base with indicator for what we were hoping for.
