Predict whether the following solutions are acidic basic or neutral. Provide explanations to support your predictions a) ammonium phosphate b) Ammonium sulfate c) Magnesium oxide
a. Which is stronger, Kb for NH3 or Ka for H3PO4.
b. Which is stronger, Kb for NH3 or Ka for H2SO4.
c. MgO + H2O ==> Mg(OH)2
Both a and b will be acidic or basic depending upon the strength of Ka or Kb. c is a hydroxide so it will be basic.
