Sodium hydroxide, tseem hu ua lye thiab caustic soda, yog ib qho inorganic compound nrog cov mis NaOH. Nws yog ib qho dawb ionic compound uas muaj sodium cations Na⁺ thiab hydroxide anions OH⁻.
Yuav ua li cas thaum sodium hydroxide yaj hauv dej?
Thaum sodium hydroxide (NaOH) yaj hauv dej, nws cais mus rau qhov zoo - them sodium ions (cations) thiab tsis zoo - them hydroxide ions (anions) … Txhua mole ntawm sodium hydroxide uas yaj yuav tsim ib mole ntawm sodium ions thiab ib tug mole ntawm hydroxide ions.
YPuas yog sodium hydroxide yaj hauv dej?
Ntshiab sodium hydroxide yog cov xim tsis muaj xim crystalline uas yaj ntawm 318 ° C (604 ° F) yam tsis muaj decomposition, thiab nrog rau qhov kub ntawm 1, 388 ° C (2, 530 ° F). Nws yog soluble hauv dej, nrog qis solubility hauv cov kuab tshuaj polar xws li ethanol thiab methanol. NaOH yog insoluble nyob rau hauv ether thiab lwm yam uas tsis yog-polar solvents.
YYuav hydroxide puas yaj hauv dej?
Txhua cov alkali hlau hydroxides yog soluble hauv dej.
Qhov txawv ntawm hydroxyl thiab hydroxide yog dab tsi?
Txawm hais tias cov ntsiab lus hydroxyl pawg thiab hydroxide pawg siv sib hloov, muaj ntau qhov sib txawv ntawm cov ntsiab lus no. Qhov sib txawv tseem ceeb ntawm hydroxyl thiab hydroxide yog uas hydroxyl tsis muaj nyob rau hauv nws daim ntawv dawb whereas hydroxide tuaj yeem pom hauv nws daim ntawv dawb li anion.
