Ph of potassium nitrite
WebAug 5, 2024 · The pH of the solution containing 0.210 M nitrous acid ( HNO₂) and 0.290 M potassium nitrite ( KNO₂) is 3.49 We'll begin by calculating the the pKa of acid. This can be obtained as follow: Acid dissociation constant (Ka) = 4.50×10¯⁴ pKa =? pKa = –Log Ka pKa = –Log 4.50×10¯⁴ pKa = 3.35 Finally, we shall determine the pH of the solution. pKa = 3.35 Webpotassium dichromate: KH 2 PO 4: potassium dihydrogen phosphate: Na 2 Cr 2 O 7: sodium dichromate: Na 2 SO 3: sodium sulfite: NaH 2 AsO 4: sodium dihydrogen arsenate: NaH 2 …
