i have 1 quart of water and i need to make it a ph of 13ish. i have 100% sodium hydroxide... how much would i have to add into the water to make it to 13?
 
dont have a test strip.. thats why im writing in here. as for the water. it should be a ph of 7. i get very clean water where im from
 
Ok, so PH 13 from NaOH. It should be about .1 mole / liter of water. So that means about 4 g of NaOH is used to make 1 liter of water 13 PH if the water is neutral. If you can't do that then you probably didn't take grade 12 chemistry.

Peace

thank you! yea.. i never did pass chem. it was the conversion parts that always got me. that never stopped me though ^^
 
If you don't mind me asking, what are you trying, or rather attempting to extract, I assume, or synthesize?

Peace
 
If its for bark, about 40g or maybe like 4 or 5 table spoons is normally enough, the pH starts diving when you pull anyway....

This is correct...which has me wondering why mhrb teks suggest adding waaay over this amount (100g for 800ml water in some cases)

Actualy even I use more than that amount, that is just the common guidline for a minimum. Once the pH starts tanking, emulsions form, and that is a bitch to deal with... an ounce of prevention and all that...

Just check and see how much lye you can get into the water before it stops melting away... I like to filter the lye water through a coffee filter before proceeding.

Remember to add it in little bits and have a cold water bucket ready to immerse your bottles in if they start getting too hot at the bottom.

But yeah, people don;t realy get how far even a few specs of lye will move the pH from neutral. nor do they realise that 13 is 6 orders of magnitude more alkaline than 7, rather than a smooth sliding scale.
 
1) If you don't have pH strips, go buy them.

2) If you can't do this.. chances are you should noy be playing with Sodium Hydroxide.
 
usually add around 6 teaspoon of lye maybe a lil more. 3 teaspoons at first then pour in some lye until i hear sound coming out of my bottles lol. ive started yielding closer to 1% for every g since i started doing 4 pulls per 1 bottle with 28g of rootbark in a single bottle (use 5 bottles all together).

anyway.. fat crystals off my 4-6th pull on first batch with 2 weeks of downtime between the 3rd and 4th pull (this is the 45g in 1 bottle). everyone seems to love the stuff. i just dont recommend my approach because i might be using too much lye and i didnt pass chem. but it works! lol

new batch in the freezer right now
its gonna be like christmas morning again
