Ii-Equation ezintathu zoLondolozo lweNdalo i-sodium hydrosulfide Izisombululo
Ngokuphathelele ukugcinwa kobuninzi kwizisombululo ze-sodium hydrosulfide, ngokusekelwe kwimigaqo yeekhemikhali kunye neenkcazo zoncwadi, kukho ubudlelwane obuthile obulinganayo phakathi kwezinto ze-sodium kunye ne-sulfur:
\(c(\text{Na}^+) = c(\text{HS}^-) + c(\text{S}^{2-}) + c(\text{H}_2\text{S})\)
Olu linganiselo luvela kwifomula yekhemikhali ye-sodium hydrosulfide (\(\text{NaHS}\)), eqinisekisa ukuba isixa esipheleleyo se-sulfur kuzo zonke iintlobo zaso sigcina isixa esimiselweyo nesixa esipheleleyo se-sodium.
Ukugcina itshaja, ngokwemigaqo ye-electroneutrality kwizisombululo ze-electrolyte (njengoko kuchaziwe kwiincwadi zezifundo zekhemistri eziqhelekileyo), itshaja iyonke elungileyo ethwalwa zii-cations kwisisombululo ilingana netshaja iyonke engalunganga ethwalwa zii-anions:
\(c(\text{Na}^+) + c(\text{H}^+) = c(\text{HS}^-) + 2c(\text{S}^{2-}) + c(\text{OH}^-)\)
Le equation ibonisa ngokuchanekileyo imeko elungeleleneyo yee-ionic charges kwisisombululo. Ngokuphathelele ukugcinwa kweproton, njengoko kuchaziwe kumaphepha ezifundo afanelekileyo kwithiyori ye-acid-base, kukho ubudlelwane obuthile phakathi koxinzelelo lwee-hydrogen ion kunye nee-hydroxide ion eziveliswa yi-water autoionization:
\(c(\text{OH}^-) = c(\text{H}^+) + c(\text{H}_2\text{S}) - c(\text{S}^{2-})\)
Oku kubonisa ngokucacileyo iinkqubo zokudluliselwa kweproton ezenzeka kwisisombululo.
