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.)

Answer 1

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.

Answer 2

I really don’t understand though. So does the acidity increase down or up the colourblind of the periodic table?

Answer 3

I really don’t understand though. So does the acidity increase down or up the column of the periodic table?
