Sodium thiosulphate reacts nrog dilute kua qaub los tsim sulfur dioxide, sulfur thiab dej. Sulfur dioxide yog cov roj uas muaj kuab lom thiab yaj tag nrho hauv cov kua dej.

Hauv qhov no, cov khoom lag luam twg muaj sodium thiosulfate?

  • Electronics.
  • Cov txheej txheem kub-plating.
  • Cov khoom siv kho mob thiab kho hniav lossis cov khoom cog.
  • Kub los yog kub-plated hniav nyiaj hniav kub.
  • Kev kho mob caj dab rheumatoid.
  • Kev kho hniav kho hniav.
  • Kub-plated intracoronary stents.

Tom qab, lo lus nug yog, ua li cas koj dilute sodium thiosulphate? Txhawm rau npaj 0.1 eq / l (los yog 0.1 mol /) sodium thiosulphate tov, yaj 24.8181 g ntawm Na2S2O3, 5H2O nyob rau hauv 500 ml ntawm freshly distilled dej (los yog freshly boiled thiab txias deionised dej) thiab 2 los yog 3 tee ntawm CHCl3 (los yog kuj 0.4 g ntawm NaOH) thiab ua kom tiav rau 1000 ml siv lub volumetric hwj.

Ntawm no, qhov concentration sodium thiosulphate cuam tshuam li cas rau tus nqi ntawm cov tshuaj tiv thaiv?

Thaum lub concentration ntawm Sodium thiosulphate tau nce lub tus nqi ntawm cov tshuaj tiv thaiv nce thiab lub sij hawm coj mus cuag equilibrium txo, yog li ntawd lub tus nqi ntawm cov tshuaj tiv thaiv yog ncaj qha proportional rau cov concentration.

Tus qauv ntawm sodium thiosulphate yog dab tsi?

Na2S2O3
