Alyuminiy gidropirofosfat tuzini hosil qilish uchun alyuminiy gidroksopirofosfat va alyuminiy trigidropirofosfat tuzlari qanday mol nisbatda reaksiyaga kirishishi kerak?

  1. 1:1
  2. 2:1
  3. 2:3
  4. 4:1

📝 Detailed explanation

Pirofosfat kislotasi: H₄P₂O₇ (4 ta almashinuvchi H)
Gidropirofosfat ioni: HP₂O₇³⁻ → AlHP₂O₇ (maqsadli tuz)
Gidroksopirofosfat: Al₂(OH)₂P₂O₇ (OH guruhi bor)
Trigidropirofosfat: Al(H₃P₂O₇)₃ (3 ta H saqlanib qolgan)
Al balans: 2x + y = z, P₂O₇ balans: x + 3y = z
2x + y = x + 3y → x = 2y
Demak, nisbat gidroksopirofosfat : trigidropirofosfat = 2:1.
