Potassium nitrite (distinct from potassium nitrate) is the inorganic compound with the chemical formula K N O 2. It is an ionic salt of potassium ions K + and nitrite ions NO 2−, which forms a …

The pH of a 0.18 M solution of KNO2 is approximately 8.30, indicating the solution is slightly basic. This value was obtained by calculating the concentration of hydroxide ions produced …

What is the pH of a 0.15 M solution of potassium nitrite (KNO2)? (The Ka value for nitrous acid (HNO2) is 4.0x10^-4). You don0t need the concentration because it will be in equilibrium. That …

Calculate the pH of a 0.35 M solution of KNO 2 (Ka = 4.0 x 10 -4). KNO 2 is a salt of a strong base KOH and a weak acid HNO 2 and therefore, the solution will be basic. Dissociate the salt …

Note: A K a of "very large" indicates a strong acid.
