Sodium hydride yog ib qho ionic compound (Na+H–). Lub ionic mobility yog negligible nyob rau hauv cov khoom lub xeev tab sis thaum melted, cov ions txav. Yog li, ua tau hluav taws xob.
NaOH puas yog tus coj zoo?
Nyob hauv lub xeev ruaj khov, sodium hydroxide tsis tuaj yeem ua hluav taws xob vim tias cov ions tsis muaj kev txav mus los. Lawv nruj nreem ntim rau hauv cov khoom siv lead ua lattice thiab nyob hauv thaj chaw. Qhov zoo tshaj plaws, lawv tuaj yeem vibrate ib ncig ntawm lawv txoj hauj lwm txhais tau tias. Vim tsis muaj kev txav ntawm ions, tsis muaj hluav taws xob conductivity hauv khoom sodium hydroxide.
NaOH puas tsim hluav taws xob?
Sodium hydroxide tsuas yog hauv daim ntawv tshuaj tuaj yeem ua hluav taws xob. Sodium hydroxide thaum nyob rau hauv cov ntaub ntawv tsis tuaj yeem ua hluav taws xob vim tsis muaj ions tso cai rau kev xa hluav taws xob los ntawm lawv. … Cov ions no muaj peev xwm ua tau hluav taws xob los ntawm kev tso hluav taws xob kom dhau los ntawm lawv.
Nah yog tus coj?
Pure sodium (Na) yog ib qho khoom siv hluav taws xob zoo vim tias 3s thiab 3p atomic bands sib tshooj los ua ib feem ntawm cov conduction bands.
NaOH ua haujlwm li cas?
Sodium hydroxide (NaOH) yog ntsev ionic. Hauv daim ntawv muaj zog, nws yuav tsis ua hluav taws xob.
