Ph of nh4br
Webb15 juli 2024 · NH4Br is an acidic salt (from a strong acid and a weak base), so the pH should be <7. Is NH4Br soluble or insoluble in water? Ammonium bromide, NH4Br, is the ammonium salt of hydrobromic acid. The chemical crystallizes in colorless prisms, possessing a saline taste; it sublimes on heating and is easily soluble in water. WebbAmmonium bromide is a weak acid with a p Ka of approximately 5 in water. It is an acid salt because the ammonium ion hydrolyzes slightly in water. Ammonium bromide is a strong electrolyte when put in water: NH 4 Br (s) → NH+ 4 (aq) + Br − (aq) Ammonium bromide decomposes to ammonia and hydrogen bromide when heated at elevated …
