Question
Balance the equation stepwise.
NaOH(aq) + H2SO4(aq) → Na2SO4(aq) + H2O(l)
Solution
NaOH(aq) + H2SO4(aq) → Na2SO4(aq) + H2O(l)
Step1: Count the number of each atom in reactant side:
Na = 1
H = 3
O = 5
S = 1
Step 2: Count the number of each atom in product side:
Na = 2
H = 2
O = 5
S = 1
Step3: Then balance the number of each atom in an equation by multiplying reactant and product side with numeral value:
If we multiply NaOH by 2 in the reactant side and H2O by 2 in the product side, then number of atoms in product and reactant side gets balance.
2NaOH(aq) + H2SO4(aq) → Na2SO4(aq) +2H2O(l)
