vinegar and baking soda will smoke up when combined, but don't breath it in. It will also unclog a sink.
It depends on what toothpaste you are using
to do this you pea in a cup and pour it in. this will extract the nitrate by preticipation and put all of the potassium at the top
You cannot do that. You can only make sodium nitrate using a different process (search Youtube) or buy it.

By using charle's perveratinas
Bacteria will seek out Nitrate as an oxygen source before using sulfate, braking the sulfide production chain in wastewater. Calcium Nitrate is one Nitrate based chemical, others include Nitrate of Soda and Potassium Nitrate.
Nitrogen gas which is created by mixing sodium azide with potassium nitrate which produces the nitrogen.
it wants to be
The solution was then cooled to 25 °C when solid potassium nitrate separated out to leave a saturated solution. Using the information provided in this question, what is the minimum mass of water that must now be added to the mixture of the solution and the solid in order to make this solid potassium nitrate redissolve at 25 °C?
calcium carbonate+ nitric acid. a strong acid would replace a weaker acid in most ionic compounds, so you would produce calcium nitrate and carbon dioxide. well, being that nitric acid is widely UNAVAILABLE to most people, it is easy to find potassium or sodium nitrate. if you are going specifically for calcium nitrate you can double displace calcium carbonate with potassium or sodium nitrate resulting in potassium or sodium carbonate and (aq) calcium nitrate. the potassium or sodium carbonate will probably precipitate out much quicker than the nitrate depending on how exact your equation for displacement is. and you should be left with (aq) calcium nitrate. boil off the water and preferably recrystallize for purity. if youre using calcium carbonate just to get any form of nitrate, i recommend simply buying potassium nitrate. if it is not assessable in your area and are trying to get an oxidizer ( i assume thats why you are trying to make a nitrate) i recommend going with a chlorate or perchlorate, these are easier to make at home through electrolysis.
Yes it would be safe to grow vegetables
Extraction has no meaning as a specific, particular process. The question makes no sense.
