Final version - But if you have any ideas to make it better let me know. Should i do more tests and reactions with the resulting potassium nitrate? Any particular ones?

There is still time to change it.

Make Potassium Nitrate and Sodium Nitrate from Calcium Nitrate - An Alternative to Ammonium Nitrate

In this video we make Potassium Nitrate and Sodium Nitrate using the easily obtained Calcium Nitrate. Potassium nitrates and sodium nitrates are sought after for their pyrotechnic uses as well as for making alternative aqua regia. I've previously shown how to make them from ammonium nitrate, but ammonium nitrate is getting harder and harder to find as stricter regulations are enacted. Fortunately it seems calcium nitrate is widely available as fertilizer and has much less restrictions. I could easily buy it online from various e-commerce vendors. Calcium nitrate by itself is usable to make nitric acid directly, but potassium nitrate or sodium nitrate themselves are specifically desired, then it can be converted. To do so, Calcium nitrate is first identified by looking at its NPK value to determine the exact form and the molar nitrate equivalent is found. That quantity is then reacted with equivalent amount of alkali, like potassium hydroxide or sodium carbonate, and then filtered. The filtrate contains the corresponding alkali nitrate that can then be dried or crystalized. For potassium nitrate specifically. Potassium chloride may be reacted with calcium nitrate and the solution heated until dissolved. Then filtered and allowed to cool and the potassium nitrate directly crystalizes out. This is filtered and retained. Although it is rather impure and needs to be recrystallized again for best purity.

Just a minor script nit-pick, around 10:00 you say "instead" twice

Good catch! Too small for me to warrant redoing the video, but thanks for pointing that out!

You have mentioned that potassium carbonate would need drying as there is a Sesquihydrate and to calculate the correct molar amounts its better working with the anhydrous salt. Sodium Carbonate is often found as Washing soda and this is the Decahydrate and you have not mentioned this in the video. If people use the molar mass from your table and work with washing soda they will get the amount wrong as the molar mass of washing soda is 286g per mole. Maybe you should have Sodium Carbonate Decahydrate in the table
