Expiation:

What happens when baking soda and vinegar are mixed.

When baking soda and vinegar are combined it has a fizzing reaction when the acetic acid in the vinegar reacts with the sodium bicarbonate ( the chemical name for baking soda). the result is some water,Sodium Acetate and can dioxide gas ( the bubbles in it) Actually what happens is the acetic acid make vinegar sour and it reacts with sodium bicarbonate a compound that’s in baking soda to form carbonic acid it’s really a double replacement reaction carbonic acid is unstable and it immediately falls apart into carbon dioxide and water it’s a decomposition reaction the bubbles you see from the reaction come from the carbon dioxide escaping that is left carbon dioxide is heavier than air, so, it flows almost like water when it overflows the container it is a gas that you exhale though in small amounts because it is a product reactions that keep your body going what’s left is a dilute solution of sodium acetate in water so that’s what happens when you mix baking soda and vinegar together this will happen.

Reflection: This was fun getting to the experiment and right what happened so now I now what happens with baking soda and vinegar are mixed and the there acetic acid this was great activity that we did in science.

My Learning Targets!

My next step is: next time try to put in a good conclusion by summing up what you have just written.

I will achieve this by: Re looking at this and learning from what i didn’t do from this work so i don’t do this in my next work.
