Titarasi Karl Fischer<\/strong> adalah kaedah titrasi yang menggunakan volumetrik atau titarimetri kumulometrik<\/strong> untuk menentukan kuantiti air yang terdapat dalam suatu analit tertentu.<\/p>\n\n\n\n

Mengapa Karl Fischer digunakan?<\/strong> Titrometri Karl Fischer (KF) adalah tindak balas redoks yang menggunakan penggunaan air semasa tindak balas untuk mengukur jumlah air dalam sampel. Ia merupakan kaedah rujukan untuk penentuan air kerana spesifisiti, ketepatan dan kelajuan pengukurannya.<\/p>\n\n\n\n

Titarasi Karl Fischer (KF) ialah teknik untuk penentuan kandungan lembapan. Ia adalah proses yang berdasarkan tindak balas iodin dengan air. Kaedah KF adalah salah satu daripada beberapa teknik yang akan mengukur kandungan air dan tidak terjejas oleh bahan mudah menguap lain.<\/p>\n\n\n\n

  Prinsip titrasi Karl Fischer adalah berdasarkan tindak balas pengoksidaan antara iodin dan dioksida sulfur. Air bertindak balas dengan iodin dan dioksida sulfur untuk membentuk trioksida sulfur dan hidrogen iodida. Titik akhir dicapai apabila semua air telah habis.<\/p>\n\n\n\n

Apakah titrator kulometrik?<\/strong><\/p>\n\n\n\n

Titrometri kulometrik ialah teknik penentuan mutlak di mana jisim sesuatu bahan ditentukan dengan mengukur kuantiti elektrik yang diperlukan untuk mengelektrolitik bahan tersebut.<\/p>\n\n\n\n

Apakah aplikasi titrasi kulometrik?<\/strong><\/p>\n\n\n\n

Reaksi Karl Fischer menggunakan titrasi kulometrik untuk menentukan jumlah air dalam sampel. Ia boleh menentukan kepekatan air pada peringkat miligram per liter. Ia digunakan untuk menentukan jumlah air dalam bahan seperti mentega, gula, keju, kertas, dan petroleum.<\/p>\n\n\n\n

Bagaimana ia berfungsi?<\/strong><\/p>\n\n\n\n

Sampel diletakkan dalam dulang berputar dan disegel. Setelah instrumen dihidupkan, sampel pertama dipindahkan ke dalam ketuhar yang dikawal suhunya. Kemudian, sampel ditusuk supaya apabila air bertukar menjadi wap, ia dipindahkan ke dalam titrator kulometrik atau volumetrik yang akan menentukan kandungan air dalam sampel. Dengan mengawal suhu, hanya air yang menguap manakala baki sampel kekal dalam botol sampel. Setelah semua air dikeluarkan dan diukur, botol sampel diletakkan semula ke kedudukan asal pada dulang, dan dulang itu berputar ke sampel seterusnya untuk diproses.<\/p>\n\n\n
