HNO2→ H+ + NO2-
KNO2→ K+ + NO2-
addition KNO2 → addition NO2-
increase/add NO2- → shift reaction to the left
increase reactant and decrease product
increase [HNO2] and decrease [H+] and [NO2-]
ionization → acquiring a negative or positive charge
addition NO2- → decrease [H+] and [NO2-] → ↓ extent ionization
At a concentration of 1 M, the weak acid HNO2 is 2% ionized and the pH of the solution is 1.7.
What happens when KNO2(s) is dissolved into the solution?
The extent of HNO2 ionization _____
the concentration of H+ _____
The pH _____
