Lets Find Out
I think that the more cups of vinegar and baking soda the bigger the eruption
When finding the measurements on how the ratio creates the eruption. I was looking for the reaction that foams or bubble. The reason to why i wanted to do this project because i love watching things erupt or making something big. I always was so curious on combining things together to see the reaction.
I did a lot of research and a lot of hands on in this project. This science fair project really did go as planed and as how i thought it was going to be. This project was fun to do.
What i predict was the ratio of 2/2 was going to produce the best eruption. At the ending of the project I notice the baking soda was getting stuck to the bottom of the bottle.
The baking soda and vinegar is a chemistry project you can use to see an effect on a real volcanic eruption. It can be an example of an acid-base reaction or this project can be just fun. People should care about their work and what others do because as of this project it is based on having things react on other uncommon items and who would not want to make things erupt? It should be fun ! This was worth doing in the first place because theirs probably a lot of young people out there that always wanted to do in science was to combine chemicals together and have them erupt.
The reaction between baking soda (sodium bicarbonate) and vinegar (dilute acetic acid) brings carbon dioxide gas. Baking soda, vinegar, carbon dioxide, water, sodium ion, acetate ion adds up altogether. First build a volcano . But before you can do all of that you would first find out what ratio of vinegar to baking soda make a big eruption. By finding that out you would have an empty bottle and put all the different ratio of vinegar to baking soda in different empty bottles and find out who has the big eruption. Then build a volcano (but you rally don’t have to build one its just makes the project fun) and put the vinegar to baking soda that has the bigger eruption in the volcano . Theirs your experiment .
What ratio of vinegar to baking soda produces the best chemical volcano eruption is good project to research because it's good to watch how a volcano erupts. This experiment relates to real life because volcano are really dangerous and can put people lives in jeopardy or even can kill them. The chemical reaction between baking soda and vinegar is the first exposure to chemical reactions that some of us wish to do when we were children. Why this is stated because baking soda and vinegar can be found in any kitchen anywhere and also because both ingredients are safe and non-toxic making it a great experiment for kids.
This experiment probably just going to tell you why does a mixture of baking soda and vinegar bubble, fizz and froth. Partly it's because it's a chemical reaction between both of them that causes the bubbling. Baking soda is really sodium bicarbonate which has the chemical formula nadco3. Vinegar is acetic acid mixed with water and has the chemical formula ch3cooh. The reason to why if we mix these objects together it bubbles and fizz from my research is because the h2co3 is carbonic acid and it quickly breaks down into carbon dioxide (co2) and water (h2o). Carbon dioxide from what is researched is what causes the bubbling and foaming when baking soda and vinegar are mixed.
Measuring Cup
Baking Soda
3(Optional) empty Container
Step 1. Measure out a half of cup (2/3) of baking soda & put it into an empty bottle.
Step 2. Measure out a half of cup (2/3) of vinegar & put it into the same bottle (but make sure you put in together.
Step 3. Just keep continuing doing the same but as you are doing it keep in mind to do as like a ratio of vinegar or a ratio of baking soda.
Step 4. Notice the maximum height reached by the foam & record (make sure to allow each reaction 30sec. to complete.)
Step 5. Soon as you reach the ration to vinegar to baking soda you want , (optional) you would have to put that into a volcano

This science-fair
project was fun. After it was all set and down i believe the
more vinegar th
ere is the most bubbles would appear and make a big
eruption. The
data was basically is the ratio telling the amount of cups there
is needed. A
t the ending of it i notice the baking soda getting stuck to the
bottom of the
bottle. So starting with the baking soda in the table i poured a
half of cup and
then poured a half of cup of the vinegar. It had a little bit of
bubbles. Then i con
tinued with what the chart said. I thought the 2/2 ratio
was going to have the
big eruption and more bubbles and it did.
This science fair project really did go as planed and as how i thought it was going to be. This project was fun to do. Also what I learn is the background of eruptions while doing this project. I also saw that the bubbles always landed on a whole number and a half. Then after I was done the baking soda was sticking at the bottom of the bottle and I think the vinegar ate some of the baking soda also.
