4. Ammoniy ionini ajratish. Yuqorida ko’rdikki, NH₄⁺ ioni K⁺ ionini hamda (KH₂SbO₄ bilan boradigan reaktsiyada) Na⁺ ionini to’ishga xalal beradi. SHuning uchun: a) K⁺ va Na⁺ ionlarini to’ishdan oldin eritmada NH₄⁺ bor yoki yo’qligini aniqlash kerak; b) agar NH₄⁺ bo’lsa, uni eritmadan butunlay yo’qotish kerak. NH₄⁺ ionini yo’qotish uchun ammoniy tuzlarining qizdirilganda eruvchanligidan foydalaniladi.
