Science - Acids and Bases
Acids and Bases
Questions:
What are the properties of acids and bases in the water?
Research Summary:
Acids and bases are in everything around us even in water. The scientific name for water is h2o. The h stands for hydrogen, the 2 stands for 2 hydrogens and the 0 stands for the oxygen. Now these are all connected, for example, if you have tasteless water and it is bland then all of the molecules are connected but they do disconnect and it will taste bitter, that is when it is more of a base than acid, but if there are too much-disconnected molecules than it is more of an acid.
Hypothesis
Hypothesized pH | 5 | 1 | 8 | 6 | 9 | 10 |
Chemical Product | Sprite | Ammonia | White Vinegar | Lemon Juice | Alcohol | Baking Soda |
-Materials:
We used:
Cabbage Juice - as the solution indicator
Sprite
Ammonia
Lemon Juice
Alcohol (Hand Sanitizer)
White Vinegar
Baking Soda
Test Tubes
Pipettes
Teaspoons
Procedure:
Set aside your indicator solution. You will use it as your "stock" solution for your experiments.
Next, you will test various household solutions with your indicator. Use one beaker for each solution you want to test because you do not want to mix chemicals that do not go well together or contaminate your results.
Place an equal portion of indicator solution and the test liquid (eg. Vinegar) into a beaker. Use a pipette to measure this.
Add drops of a liquid you want to test until you see the solution change in colour. Gently swirl the cup as you add the drops, being careful not to spill the solution.
Record the observed pH and a description of
each solution in a data table in your lab notebook.
Analyze your results. How does the pH of the different household items you tested compare to each other? Are you surprised by any of your results?
Observations/Results:
Actual pH | 3 | 11 | 3 | 2 | 6 | 8 |
Observed Colour | Violet | Green | Pink | Red | Purple | Blue |
Chemical Product | Sprite | Ammonia | White Vinegar | Lemon Juice | Alcohol | Baking Soda |
Discussion:
For the baking soda experiment, it reacted differently. The baking soda absorbed some of the cabbage juice and made it turned into a light blue, but the leftover that was sitting on top, it turned a dark blue.
With the Alcohol, we used hand sanitizer so it also was different from the other experiments. Hand sanitizer is quite gluggy, so it floated up to the top and some of it still stayed the same only if you didn’t stir it around.
Now with the ammonia, it reacted completely differently. As soon as we tipped the cabbage juice into the ammonia, it foamed up fully and then it calmed down and then changed colour completely.
Conclusion:
For this experiment, all of the chemicals reacted really differently and worked perfectly perfect. It wasn’t what we all expected but it worked very well as we got a lot of evidence.

Avengers Endgame
They all have different skillsets and mindsets like Thor is the god of thunder but Tony Stark is a billionaire with a robot for his self-defence and his amazing tech.
The background also represents the main place where all of the events happen.
The gauntlet represents Thanos and the power that he has with all of the stones. It also means that Thanos and the Avengers will face off.

Binary / ASCII
What do you think? Have you ever tried encoding anything in binary or ASCII? Could you have a try for yourself? Can you work out how to write my initials in ASCII from the pattern above?
