2-tajriba. Dissotsialanish darajasining elektrolit tabiatiga bogliqligi.

Ikkita probirkaga 2-3ml dan 0,1n hlorid va sirka kislotasi eritmasidan quyib, ikkala probirkaga bir hil miqdorda rux bo’lakchalarini soling. Har bir probirkadagi vodorod gazining ajralib chikish tezligiga etibor bering. Reaksiyalar orasidagi farqni izohlang. Reaksiya tenglamalarini tuzing.

3-tajriba. Elektrolit eritmalarida kimyoviy muvozanatning siljishi.

Ikkita probirkaga 2 – 3 ml dan sirka kislotasining 0,1n eritmasidan kuying va ularga indikator kog’ozi tashlang. Probirkalardan biriga natriy atsetat tuzi kristalidan tashlang va probirkalarni solishtiring. Eritma ranggi o’zgarishini tushuntiring.
