(Reupload) Make Potassium Nitrate and Sodium Nitrate at Home Using Calcium 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 uses in... umm.. fertilizer.... 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.

We're just making fertilizer, that's it, completely normal fertilizer. Nothing special. Just fertilizer...

No wonder the food industry is booming... I mean blooming, BLOOMING!

I got a scholarship for a chemistry bachelors and masters degree program today. Thanks for doing what you do.

YouTube's policies are also made from fertilizer, this video is a great method! It's much cleaner and has far less odour than the fertilizer method used by YouTube. 👍

I love a completely normal video *ABOUT FERTILIZER YOUTUBE. THIS IS MY FAVORITE FERTILIZER-CENTRIC VIDEO. I SURE DO HOPE IT STAYS UP AND UNRESTRICTED FOR ME TO CONTINUE WATCHING FOR MY FERTILIZER NEEDS!!*

I started watching this channel at university when I was taking organic chemistry 11 or so years ago. Hands down the best chemistry channel on this platform. Excellent work.

screw YouTube, I'll gladly watch again a NurdRage video to help recover views.

Plus you are my favorite Chemist the end.

[vincejohnm]

Your favorite chemist’s favorite chemist.

Ive been watching these videos since the OG Days of Glowsticks and sneaking around behind the ex-lab’s nosier colleagues 😂 I was no older than 12 when I came across this channel, and I’m proud to say I’ll be a father in less than 3 months. Can’t wait to make glowsticks and fertilizer with them😊

By YT's hilarious "standards, " we gotta restrict anything that involves sugar too. It's been known that many serial killers and other mass murderers had it in their blood stream at the time of their crime.

Thanks, my... crops will love this pure fertilizer...

[arahatchikkatur]

I used this process with sodium carbonate and calcium ammonium nitrate and was able to get 147g (~58% yield). Very useful video indeed for some great fertilizer

❤ Thanks and I hope this goes viral on All the "prepper" channels 👍.
It's quite amazing how you can find "nitrates" pretty easy.
I've been using a local pool place for most of my supplies so I definitely appreciate your help in my pyrrrr'plant "fertilizer" experiments.
Always fun learning chemistry ❤👍🇱🇷

I have discovered your channel recently as I have stumbled into the wonderful world of amateur chemistry. This came as a result of thirst for knowledge to understand how my electrolytes worked during my last endeavor into the the fascinating hobby of electroplating. Thank you for all the work you do. Your content, whilst not as polished as some others, Is extremely well done, I find your content informative and to the point with minimum fluff. You consistently provide clear instructions and detailed explanations. I watch a many technical channels on YT as my hobbies and interests cover a lot of territory. I must say that yours is Quite possibly the best chemistry channel on the platform, for just pure knowledge conveyance and ease of absorption, well In my opinion anyways. Chemistry is amazing and I think you do an amazing job at instruction. Felt that needed to be said. Appreciate the hard work, Please Keep em' comin. Liked & Subscribed!
Shout out from Canada! Nurd Rules!

Always a good day when a new nurdrage vid is out, even if it's a tweek of a old one

[grannetia]

Thanks for re uploading, the knowledge of creating fertiliser should available to all. 😊

[NathanaelNewton]

This keeps getting recommended to me over and over and over again. I might as well watch it 😂

[bencapobianco]

Love NurdeRage! I have learned so much from this channel!! It was my first chemistry channel subscription and really got me into how cool it is about 7 years ago

[Angel_the_Bunny]

Thank you for the amazing py.... Fertilizer! video!

[trimethoxy]

shall this video be at the top of the list! let gardeners of the world know how to make fertiliser they need!
