What is the general trend in the acidity of Period 3 oxides moving across the Periodic table from left to right? (Be sure to refer to the term acidity.)
Generally the trend is to increase the acidity. For example look at the results if you add H2O to the oxide.
Na2O gives NaOH a strong base.
MgO gives Mg(OH)2, a weaker base (stronger acid)
P2O5 gives H3PO4, a weak acid
SO3 gives H2SO4, a strong acid.
Cl2O7 gives HClO4, a very strong acid.
