Question: 1). Write the equilibrium in water for each compound. 2) Find the Ka (pKa) or Kb () in the table to determine whether the substance
1). Write the equilibrium in water for each compound.
2) Find the Ka (pKa) or Kb () in the table to determine whether the substance behaves as a weak acid or base; otherwise it will be a strong electrolyte.
3) Calculate the concentration of H30* and the pH of the resulting solution.
