Ishqor bilan gazlar ekvimolyar (teng mol miqdor) nisbatda reaksiyasi natijasida nordon tuzlar hosil bo'ladi:

SO2 + NaOH = NaHSO3

CO2 + NaOH = NaHCO3

Hosil bo'lgan NaHSO3 eritmasi lakmus rangini qizilga, NaHCO3 eritmasi esa ko'k rangga bo'yaydi.

ilmiy izoh: tuz tarkibida H borligi uchun nordon (ะบะธัะปั‹ะน) tuz deb nom berganmiz, go'yoki bunday tuzlar eritmasi tabiati doimo kislotali tabiatga (pH<7) ega sifatida qaralganday. Ammo, ilmiy tadqiqotlar shuni ko'rsatdiki, nordon tuzlarning barchasi kislotali tabiatga ega emas. Sababi, bunday tuzlarda bir vaqtning o'zida 2 xil jarayon kuzatiladi, ya'ni dissotsilanish va gidroliz:

HX(-) <โ€”> H(+) + X(2-) Km1

HX(-) + H2O <โ€”> H2X + OH(-) Km2

Bu jarayonlar qaytar jarayonlar (kimyoviy muvozanat) bo'lib, eritma muhitining tabiati Km qiymatiga bog'liq bo'ladi: Km1>Km2 kislotali; Km1<Km2 asosli.

Nega eritmada muhit har xil โ€” ya'ni NaH2PO4 kislotali, Na2HPO4 esa aksincha asosli?

๐Ÿ’š๐Ÿ’š๐Ÿ’š
Eritma muhitida mazkur kuchsiz kislota qoldiqlari ikki yo'nalishda:
1) gidroliz konstantasi
2) dissotsioanish konstantasi
natijasida qayta ionlar taqsimoti vujudga keladi. Km asosida esa muhit (pH) kelib chiqadi. Jumladan:

โ–ถ๏ธNaH2PO4
1) H2PO4(-) + H2O = H3PO4 + OH-
Km1=1,4*10(-12)
2) H2PO4(-) = HPO4(2-) + H+
Km2=6,2*10(-8)

Km1<Km2, xulosa: muhit kislotali

โ–ถ๏ธNa2HPO4
1) HPO4(2-) + H2O = H2PO4(-) + OH-
Km1=1,6*10(-7)
2) HPO4(2-) = PO4(3-) + H+
Km2=5,0*10(-13)

Km1>Km2, xulosa: muhit asosli
