Popular questions
Is potassium carbonate soluble?
Yes—it's highly soluble in water and deliquescent. It is insoluble in ethanol.
Is potassium carbonate soluble in water?
Yes, it dissolves readily in water to form a strongly alkaline solution.
What is potassium carbonate used for?
In foods, E501(i) is used as a stabiliser and acidity regulator/buffer, and as a leavening aid in some baked goods and alkaline-processed foods like certain noodles and cocoa. It’s also used industrially in making glass and soap.
Is potassium carbonate dangerous?
At approved food-use levels it’s considered safe, but the solid and concentrated solutions are strongly alkaline and can irritate or burn skin and eyes. Those with kidney disease or on potassium‑sparing medications should avoid excessive potassium intake.
How to make potassium carbonate?
Industrial production absorbs carbon dioxide into potassium hydroxide solution to form K2CO3; historically it was obtained from leached wood ashes. For food use, only purchase certified food‑grade material—home production isn’t recommended.
1 gram of aluminum will produce how many grams of potassium aluminum sulphate dodecahydrate?
About 17.6 g, assuming the aluminum is fully converted to potassium alum dodecahydrate (KAl(SO4)2·12H2O) using potassium sulphate (E515i) and sulfuric acid at 100% yield.
1..00 gram of aluminum will produce how many grams of potassium aluminum sulphate decahydrate?
About 16.3 g if the product is the decahydrate (KAl(SO4)2·10H2O) at 100% yield.
Assumming a 100 yeild 1 gram of aluminum will produce how many grams of potassium aluminum sulphate?
About 17.6 g as the common dodecahydrate; if you mean anhydrous KAl(SO4)2, it’s about 9.6 g per 1 g Al (both at 100% yield).
How much "potassium sulphate" should i apply to raise *ppm?
K2SO4 is 44.9% potassium by weight, so grams needed ≈ 0.00223 × desired K ppm × volume in liters (e.g., raising K by 10 ppm in 100 L needs ~2.23 g K2SO4).
How much potassium is in glucosamine sulphate?
In the common glucosamine sulfate 2KCl form, potassium is about 13% by weight (≈195 mg K per 1500 mg); sodium-chloride–stabilized forms contain no potassium.
