Crazy Currents by TC.

Question: Where is the gas formed during the chemical reaction of vinegar and baking soda and how we can see this.
Hypothesis: The gas is formed as bubbles inside the mixture.
Equipment: Baking Soda, Vinegar, Sultanas, Measuring Spoon and Containers.
1) The vinegar is poured into the container.
2) The sultanas are added.
3) The baking soda is sprinkled into the container.
1) Bubbles are formed when the vinegar and baking soda is mixed.
2) The sultanas traveled to the top of the bubbles and then down.This is repeated until all the bubbles have diapered.
Explanation: The sultanas moved to the top because of Carbon Dioxide formed under the sultanas and then pushed to the top.At the top the bubbles popped and released gas causing the sultanas to fall.This process is repeated until there is no more bubbles.

This Proves:
The gas is formed as bubbles inside the mixture.P.S the the gas Carbon Dioxide, scientists call it CO2.

    I like the 'This proves' comment you have added onto your explanation. So your hypothesis was correct then?
