নেসলার'স রিএজেন্ট দ্বারা নিচের কোন ক্যাটায়ন (Cation) শনাক্ত করা যায়?
নেসলার রিএজেন্ট (K 2 HgI 4 ) হল একটি দ্রবণ যা সোডিয়াম হাইড্রোক্সাইড এবং পটাসিয়াম আয়োডাইডকে মার্কিউরিক ক্লোরাইড বা পারদ আয়োডাইডের সাথে একত্রিত করে প্রস্তুত করা হয়। বায়বীয় অ্যামোনিয়ার সাথে বিক্রিয়া করলে তা বাদামী ধোঁয়া উৎপন্ন করে। অ্যামোনিয়ার দ্রবণের মধ্য দিয়ে যাওয়ার সময় এটি একটি নোংরা বাদামী অবক্ষেপ তৈরি করে।
