Question: why does baking soda affect how much carbon dioxide is produced when u mix it with vinegar?
need for a science lab experiment. just what does baking soda do in the process
Answer: Its an acid base reaction. The baking soda (sodium bicarbonate) is a base and neutralizes the acid in the vinegar (acetic acid) and releases carbon dioxide in the process.
Here is the reaction :
NaHCO3 + CH3COOH ———> NaCH3COO- + H2O + CO2
Diet Coke + Mentos
Question: Is this a good science fair topic? I want to involve children?
Alright. I can’t believe that its the first week of school and I have to have 3 Science Fair Ideas by friday. I am in 9th grade so I need a high school level project. My mom is the owner/director of a preschool. So I wanted to use children in my experiment. (Yes, I know I have to get the human subject forms and everything) I was thinking about doing how does food affect memory. And feed them like cheetos one day and test them and then blueberries (a brain boosting food) the next day and test them. Is this a good topic? If you have any other ideas please let me know. I would like to avoid doing something with color because the teacher used that as an example. You tweak my experiment or even completely change it. I would like to use humans.
Thanks for the help! and sorry if it was long(:
Answer: great idea but experiment with diferent kinds of foods not just chetos and blue berrys try tomatos or carrots too as these have some intresting propertys tht may come into play but use your reserch and imagination and make shure to have a controll of students that havent eaten annything yet i would do at least 5 foods plus a controll
