You can mix this powders with RO water and then add it in this form. That's how I've been doing it for a long time now. Only problem is you need to shake or mix it every time.
3.6g Potassium Bicarbonate (KHCO3) in 100 litres (26.417 US Gallons) of water will raise the dKH by 1Would kh2co3 be preferable over k2co3 for raising KH?
Ya I understand that part of it, but I just see most people suggesting the bicarbonate form. Maybe its more readily available?3.6g Potassium Bicarbonate (KHCO3) in 100 litres (26.417 US Gallons) of water will raise the dKH by 1
2.4g Potassium Carbonate (K2CO3) in 100 litres (26.417 US Gallons) of water will raise the dKH by 1
Either would work. Would depend on what prices you could get either for as to which would be more cost effective. For me, on eBay, I could get Potassium Carbonate for the same price as Potassium Bicarbonate, so I just get Potassium Carbonate, which would treat more gallons/raise more KH, by weight.
Though, maybe some might prefer the smaller KH increments that would be easier to measure out with Potassium Bicarbonate?
I'm no expert, but I believe they would both be equally soluble?Ya I understand that part of it, but I just see most people suggesting the bicarbonate form. Maybe its more readily available?
Thanks for the reply Darkblade.No, I believe bicarbonates are generally more soluble than carbonates.
Bicarbonates tend to be more readily available than carbonates (not sure about pricing). With regards to the "potency" I did not work out the molar concentrations, but this is an exercise left to the reader (or you can just Google it).
Yes, baking sodium bicarbonate will decompose it into sodium carbonate.
Thanks for the reply Darkblade.
Could you do the same, baking Potassium Bicarbonate to create Potassium Carbonate?
Again, I'm no chemist so I have no idea if anything is ignitable or if the same would apply (I would imagine so).
Found these about solubility
INTRODUCTION TO CHEMISTRY OF CARBONATES & BICARBONATES
Too tired to read them right now, so will get back to that later.
Does it state anywhere the solubility of how many grams of bicarb vs carb can be dissolved in X amount of water?
Just from knowing that dissolved form would only be bicarbonates, wouldn't they have the same solubility?
Lol, I need to get some rest and research it.
