#### Solution

NaOH(aq) + H_{2}SO_{4}(aq) → Na_{2}SO_{4}(aq) + H_{2}O(l)

Step1. Count the number of each atom in reactant side:

Na= 1

H=3

O=5

S=1

Step2. 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 H_{2}O by 2 in the product side, then number of atoms in product and reactant side gets balance.

2NaOH(aq) + H_{2}SO_{4}(aq) → Na_{2}SO_{4}(aq) +2H_{2}O(l)
