As an acid sulphur dioxide reacts with sodium hydroxide solution to form a salt called sodium sulphate Na2SO3 and water. Write a balanced chemical equation for the reaction (show state symbols)?
1 Answer
Explanation:
Now, a balanced equation of a reaction has equal atoms of each element on both sides. So we count the atoms each element.
-
We have
#1# atom of Sulphur on the one side (#SO_2# ) and#1# on the other side (#Na_2SO_3# ). -
We have
#3# atoms of Oxygen on the one side (#SO_2# and#NaOH# ), but#4# on the other side (#Na_2SO_3# and#H_2O# ). -
We have
#1# atom of Sodium (#NaOH# ), but#2# on the other side (#Na_2SO_3# ). -
We have
#1# atom of Hydrogen (#NaOH# ), but#2# on the other side (#H_2O# ).
So to balance it:
