Question

Name the products formed when the following oxides are dissolved in water write the balanced equation
a sulphur dioxide
b potassium oxide
c carbon dioxide
d calcium oxide

Answer 1

SO2+H2O=H2SO3

K2O+H2O=2KOH

CO2+H2O=H2CO3

CaO+H2O=Ca(OH)2

is the right........

Answer 2

Name the products formed when the following oxides are dissolved in water write the balanced equation

a sulphur dioxide

b potassium oxide

c carbon dioxide

d calcium oxide

So the answer is Sulphur dioxide (SO2) dissolves in Water (H2O) and make Sulphurous acid (H2SO3).

H2O(l) + SO2(g)= H2SO3(aq).

This is the right answer to your question. Hope it helps you with what you are looking for.
