Works for me
I successfully use this to raise the pH of food stuffs. I bought it in February 2024, and my sensitive nose could not detect any smell. I use it for hydrating faba bean protein concentrate and for an alkaline brine for hydrating beans (1 cup dry beans, 700mL water, 28g salt, 7g K-carb; 8–9 hrs room temp + 10–11 hrs in fridge). I do use a citric acid stop bath (4g/2.5c water) for 5 minutes to freshen the beans up and then they taste great. Now you know my secret!

Smells perfumy
I would reach out to the company before submitting this review, but I saw no way to do so. This is the second time I purchased this product. This time, I noticed a perfumy smell to it that I had not noticed before. Did I just miss it the first time? I don't think so. Especially since I researched K2CO3 and discovered it is supposed to be odorless. I use this for a food product, and do not want any artificial perfumes in it.

I bought this by mistake
I purchased this by mistake, I was supposed to buy calcium chloride, and somehow ended up buying this. With that said, it came in a thick clear plastic bag, the quality was nice, pure white, consistent color, and clearly labeled as the proper chemical compound.

Seems to be what it is
I haven't gotten to do any real testing yet but I have salted some ethanol with it an it seemed to work ok? Cheapest price on Amazon an fastest shipping but still a bit steep but what isn't these days. Everything is at LEAST 2 dollars more then it should be.

Good for pH control
I add a bit of this to my plant feeding regimen to keep the pH from getting too low.

This works wonderfully on lawns, to add the K of NPK. It also acts as a very fast adjuster of pH. If you have an acidic soil, you know calcium carbonate (dolomite limestone powder) takes a long time to raise the pH and make the soil less acidic. I added at the rate of 1 gram per square ft, in a shaded lawn, and the results were much greener grass, with better nutrient uptake from the potassium, as well as reduction in the negative effects of acidic soil.
