Problem 1

How are oxidation numbers assigned?

Step-by-Step Solution:
Step 1 of 3

Common Ion Effect Common ion-effect: the extent of ionization of a weak acid decreases in the presence of a strong electrolyte that shares a common ion (same holds for a weak base) - If you were to add Ca(NO3)2 to the original equation above. . . nothing would occur because there is no common ion and would have no effect on the NO2 + H- + - If you were to add HNO3 to the original equation above. . . the+equilibrium would shift to the left and make more HNO2 to compensate for the increase of H Buffers Buffers: solution of a weak acid and it’s conjugate base or a weak base and its conjugate acid - buffers resist changes in pH when a amount of acid or base is added - ex: CH3COOH/CH3COONa NH3/NH4Cl HNO2/KNO2 Henderson-Hasselbalch Equation
