Ujian api

Flame test

Ujian nyala adalah prosedur analitik yang digunakan dalam kimia untuk mengesan kehadiran unsur-unsur tertentu, terutamanya ion logam, berdasarkan spektrum pelepasan ciri setiap elemen. Warna api pada umumnya juga bergantung kepada suhu; lihat warna api. Ujian ini melibatkan memperkenalkan sampel unsur atau kompaun kepada api yang panas, tidak bercahaya, dan memerhatikan warna nyalaan yang menghasilkan. Idea ujian adalah bahawa atom sampel menguap dan kerana ia panas, mereka memancarkan cahaya ketika berada di api. Contoh pukal memancarkan cahaya juga, tetapi cahaya tidak baik untuk dianalisis. Contoh pukal memancarkan cahaya terutamanya disebabkan oleh pergerakan atom, oleh itu spektrumnya luas, terdiri daripada pelbagai warna. Atom berasingan sampel yang hadir dalam api boleh memancarkan hanya disebabkan oleh peralihan elektronik antara tahap tenaga atom yang berbeza. Peralihan tersebut memancarkan cahaya frekuensi yang sangat spesifik, karakteristik unsur kimia itu sendiri. Oleh itu, api mendapat warna, yang ditentukan terutamanya oleh sifat-sifat unsur kimia bahan yang dimasukkan ke dalam api.

A flame test is an analytic procedure used in chemistry to detect the presence of certain elements, primarily metal ions, based on each element's characteristic emission spectrum. The color of flames in general also depends on temperature; see flame color. The test involves introducing a sample of the element or compound to a hot, non-luminous flame, and observing the color of the flame that results. The idea of the test is that sample atoms evaporate and since they are hot, they emit light when being in flame. Bulk sample emits light too, but its light is not good for analysis. Bulk sample emits light primarily due to motion of the atoms, therefore its spectrum is broad, consisting of a broad range of colors. Separate atoms of sample present in flame can emit only due to electronic transitions between different atomic energy levels. Those transitions emit light of very specific frequencies, characteristic of chemical element itself. Therefore, the flame gets the color, which is primarily determined by properties of the chemical element of the substance being put into flame.
