APAKAH MAKSUD ROCHELLE SALT dalam CORSICA?
Potassium sodium tartrate
Potassium sodium tartrate adalah garam double yang pertama kali disediakan oleh apothecary, Pierre Seignette, La Rochelle, Perancis. Hasilnya garam dikenali sebagai garam Seignette atau garam Rochelle. Garam Rochelle tidak boleh dikelirukan dengan garam batu, yang merupakan bentuk mineral natrium klorida sahaja. Potassium sodium tartrate dan monopotassium fosfat adalah bahan pertama yang ditemui untuk mempamerkan piezoelectricity. Harta ini membawa kepada penggunaannya yang luas dalam pickup "kristal" gramophone, mikrofon dan earpieces semasa ledakan elektronik pengguna pasca Perang Abad ke-20. Transduser sedemikian mempunyai keluaran yang sangat tinggi dengan keluaran kartrij pick-up biasa sebanyak 2 volt atau lebih. Garam Rochelle adalah deliquescent jadi mana-mana transducers berdasarkan bahan merosot jika disimpan dalam keadaan lembap. Ia tidak berwarna ke garam biru-putih yang mengkristal dalam sistem ortorombik. Rumus molekulnya ialah KNaC4H4O6 · 4H2O. Ia agak larut dalam alkohol tetapi lebih larut sepenuhnya dalam air. Ia mempunyai graviti spesifik kira-kira 1.79, titik lebur kira-kira 75 ° C, dan mempunyai salin, rasa sejuk. Sebagai aditif makanan, nombor Enya adalah E337.
