[Egrowth] uji garam beryodium

[Hermin Halim]

saya ingin coba jawab pertanyaan yang kedua dulu. cara
menguji yodium bisa dengan cara titrasi iodometri,
jadi garam beryodium (yang mestinya mengandung kalium
iodat) dititrasi dengan kalium iodida yang sudah
dibakukan, sampai terbentuk warna kekuningan.warna
kuning terjadi karena terbentuk iodium (I2). bisa juga
dalam erlenmeyernya dikasi kloroform sehingga warnanya
akan menjadi ungu dan tampak lebih jelas.

salam,
hermin
