Popular questions
Is h2so4 a strong acid?
Yes—sulfuric acid (H2SO4) is a strong diprotic acid; its first proton dissociates completely in water.
What is sulfuric acid used for?
As a food additive (E513), it’s used as an acidity regulator and processing aid for pH control, sugar refining, and starch modification; industrially it’s used for fertilizers, batteries, and chemical synthesis.
Is h2so4 an acid or base?
An acid—specifically a strong diprotic mineral acid used to acidify and catalyze reactions.
Is sulfuric acid a strong acid?
Yes; it’s considered a strong acid, with essentially complete first dissociation in water.
What does h2so4 do in a reaction?
It donates protons to acidify mixtures and can catalyze hydrolysis, esterification, and dehydration; in food processing it’s mainly used to adjust pH and is neutralized or removed afterward.
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.
