Sampel kalium nitrat

Kalium nitrat ya iku senyawa kimia kanthi rumus kimia KNO3 . Iki minangka uyah ion saka ion kalium K+ lan ion nitrat NO3-, mula nitrat logam alkali. Kasedhiya ing alam minangka mineral, nitriter (utawa nitre ing Inggris). [6] Iki minangka sumber nitrogén, lan nitrogén dijenengi miturut niter. Kalium nitrat minangka salah sawijining senyawa sing ngandung nitrogén sing sacara kolektif diarani saltpetre (utawa saltpeter ing Amerika Utara).[6]

Efesus utama kalium nitrat yaiku ing pupuk, ngilangi puntung wit , propelan roket lan kembang api. Iki minangka salah sawijining unsur utama bubuk mesiu (bubuk ireng). [7] Ing daging olahan, kalium nitrat ditanggepi karo hemoglobin lan myoglobin sing ngasilaké warna biru.[8]

Ètimologi[besut | besut sumber]

Amarga panggunaan lan produksi awal lan global, kalium nitrat, duwé akèh jeneng. Ing tembung Ibrani lan Mesir sing diarani duwé konsonan n-t-r, nuduhaké kemungkinan ana gegayutan ing nitron Yunani, saka Latin dadi nitrum utawa nitrium. Perancis kuna, tembung niter lan tembung nitre ing Inggris Tengah. Ing abad kaping 15, wong Eropa ngarani saltpetre [9] lan mengko minangka nitrat potash, amarga kimia senyawa kasebut luwih dingerteni. Ing Arab disebut iku "salju China " ( Arab: ثلج الصين‎‎ thalj al-ṣīn ). Zat iki disebut "uyah Cina" dening Iran / Persia [10] [11] [12] [13] [14] utawa "uyah saka uyah rawa-rawa China" ( Pèrsi: نمک شوره چينی‎‎ namak shūra chīnī ). [15] [16]

Guna kalium nitrat[besut | besut sumber]

Kristal kalium nitrat

Oksidator[besut | besut sumber]

Panggunaan kalium nitrat sing paling misuwur bisa uga minangka oksidator ing bubuk ireng. Wiwit jaman kuna nganti pungkasan taun 1880-an, bubuk ireng nyedhiyakaké kekuwatan kanggo kabeh senjata api ing donya. Sawisé wektu kasebut, senjata cilik lan artileri gedhe wiwit gumantung karo bahan peledhak, bubuk tanpa asap. bubuk ireng isih digunakaké saiki ing motor roket bubuk ireng, nanging uga digabung karo bahan bakar liyané kaya gula ing "permen rokèt". Iki uga digunakaké ing kembang api kayata bom asap. [17] Iki uga ditambahaké ing rokok kanggo njaga kobongan tembakau [18] lan digunakaké kanggo mesthekaké kobong kartrid kertas kanggo revolver tutup lan bal. [19] iki uga bisa digawé panas nganti pirang-pirang atus derajat kanggo digunakaké kanggo niter bluing, sing kurang awét tinimbang oksidasi proteksi liyané, nanging ngidini pewarnaan bagéan-bagéan baja sing khusus lan asring apik, kayata sekrup, pin, lan bagéan cilik liyané senjata api.

Pangolahan daging[besut | besut sumber]

Kalium nitrat minangka bahan umum saka daging asin wiwit jaman kuna [20] utawa Abad Pertengahan. [21] Adopsi panggunaan nitrat sing nyebar luwih anyar lan ana gandhengané karo pangolahan pangolahan daging kanthi gedhé. [22] Panggunaan kalium nitrat umume dihentikan amarga asil alon lan ora konsisten dibandhingaké karo senyawa natrium nitrit kayata "bubuk Prague" utawa "uyah jambon". Sanajan mangkono, kalium nitrat isih digunakaké ing sawétara pangaplikasian panganan, kayata salami, ham sing wis garing, charcuterie, lan (ing sawétara negara) ing banyu asin digunakaké kanggo nggawé daging sapi kornet (kadhang-bareng karo natrium nitrit ). [23] Nalika digunakaké minangka aditif panganan ing Uni Eropa, [24] senyawa kasebut diarani E252 ; iki uga disétujoni kanggo digunakaké minangka aditif panganan ing Amerika Serikat [25] lan Australia lan Selandia Baru [26] (sing didaftar ing nomer INS 252).

Pupuk[besut | besut sumber]

Kalium nitrat digunakaké ing pupuk minangka sumber nitrogén lan kalium - loro makronutrien kanggo tanduran. Yèn digunakaké dhéwéan, rating NPK yaiku 13-0-44. [27] [28]

Farmakologi[besut | besut sumber]

  • Digunakaké ing sawétara pasta untu kanggo untu sensitif. [29] Bubar iki, panggunaan kalium nitrat ing pasta untu kanggo ngobati untu sensitif wis saya tambah. [30] [31]
  • Digunakaké kanthi historis kanggo ngobati panandhang asma. [32] Digunakaké ing sawétara pasta untu kanggo ngatasi gejala asma. [33]
  • Digunakaké ing Thailand minangka bahan utama ing tablet ginjel kanggo ngatasi gejala cystitis, pyelitis lan urethritis. [34]
  • Nglawan tekanan getih dhuwur lan sapisan digunakaké minangka hipotensi. [35]
