Zat kimia

Zat kimia^[1] atau bahan kimia, nan dikana juo sabagai zat murni adolah suatu bantuak materi nan punyo komposisi kimia dan sifaik karakteristik konstan.^[2] Iko indak dapek dipisahkan manjadi komponen jo metode pamisahan fisika, iyolah tanpa mamutuih ikatan kimia.^[3] Zat kimia dapek barupo unsua kimia, senyawa kimia, ion atau paduan. Zat kimia salalu disabuik 'murni' untuak mambedakannyo dari campuaran. Contoh umum zat kimia iyolah aia murni; iko punyo sifaik nan samo dan parbandiangan hidrogen tahadok oksigen nan samo, baiak diisolasi dari sungai maupun dibuek di laboratorium. Zat kimia lain nan biaso dijumpo dalam bantuak murni iyolah intan (karbon), ameh, garam meja (natrium klorida) dan gulo pasia (sukrosa). Namun, pado praktiknyo, indak ado zat nan sapanuahnyo murni, dan kamurnian kimia ditontuan sasuai jo panggunoan zat kimia nan dimaksuik. Zat kimia barado sabagai zat padek, caiaran, gas, atau plasma, dan dapek baubah antaro fase materi iko jo parubahan suhu atau tokanan. Zat kimia dapek digabuangkan atau diubah manjadi zat lain malalui reaksi kimia. Bantuak energi, ajak cahayo dan paneh, bukan materi, dan basobok dalam hal iko bukan tamasuak "zat".
