Wadatacce
A tushen sinadarai shine duk wannan sinadarin da ke narkarwa yana sakin ions hydroxyl (OH–). Hakanan ana kiran sansanonin sinadarai da alkalis, saboda ta rarrabuwa da sakin ƙungiyoyin hydroxyl, da pH na mafita yana ƙaruwa, wato, maganin ya zama alkaline. Wannan ya sabawa abin da ke faruwa lokacin da a acid, saboda a cikin wannan yanayin pH yana raguwa kuma maganin ya zama acidic.
The tushe suna da dandano mai ɗaci mai ɗaci. Bayan narkewa, mafita sakamakon yana gudanar da wutar lantarki (saboda kasancewar ions) da yawanci suna caustic kuma suna fusata fata da sauran kayan jikin mutum da na dabbobi.
Tushen suna kawar da acid, galibi suna yin gishiri. Maganganun alkaline sukan ji daɗin santsi ko sabulu; Wannan yana faruwa saboda nan da nan suna samar da saponification na mai gabatar a farfajiyar fata.
The solubility na hydroxides ya dogara da karfe: waɗanda ke cikin rukuni (I) sune mafi narkewa a cikin ruwa, a gefe guda, hydroxides na abubuwan da ke da ƙima (II) ba su da ƙarfi . Amines da nucleic acid tushe sune mafi tartsatsi daga tushen asalin.
Amfani da tushe
Ana amfani da sinadarin sodium hydroxide a masana'antu: shi ake kira caustic soda. A cikin masana'antar sabulu ana amfani da kitsen dabbobi ko kayan marmari, waɗanda ake tafasa da su hydroxide sodium, don haka an kafa sodium stearate.
Hakanan ana amfani da sinadarin sodium hydroxide wajen kera masu tsabtace tanda, wajen kera takardar takarda da wasu masu tsabtace gida. Wani tushe mai amfani da yawa shine alli hydroxide, wanda shine lemun tsami kashe wanda ake amfani da shi wajen gini.
