Consider the following oxides: SO2, Y2O3, MgO, Cl2O, and N2O5. How many are expected to form acidic solutions in water? Consider the following oxides: , , , , and . How many are expected to form acidic solutions in water?

Respuesta :

Answer:

Three of the five oxides are expected to form acidic solutions in water

Explanation:

We have different types of oxides : Acidic oxides, Basic oxides, Amphoteric oxides, Peroxides and Higher oxides.

Only acidic oxides will dissolve in water to give an acidic solution.

Considering the given oxides carefully,

  • SO2 will dissolve in water to produce H2SO3 which is acidic.

  • Y2O3 will dissolve in water to produce Yttrium(III) hydroxide which is basic.

  • MgO will dissolve in water only to produce Mg(OH)2 which is also basic.

  • Cl2O dichlorine mono oxide will dissolve in water to produce HClO which is acidic.

  • N2O5 will dissolve in water to produce HNO3 which is also acidic.

Metal oxides form basic solutions while nonmetal oxides form acid solutions.

Metals occur towards the left hand side of the periodic table. Metals react with oxygen to form oxides. The oxides of metals dissolve in water to form basic solutions. The oxides that are expected to form an basic solution are; Y2O3, MgO,

Nonmetals also react with oxygen to form oxides. The oxides of nonmetals dissolve in water to yield acids. Hence, the oxides that are expected to form acidic solutions are;SO2, Cl2O, and N2O5.
