Question

NaOH (aq) + H₂SO₄(aq) →Na₂SO₄(aq) + H₂O(1) , Balance the equation stepwise

Answer 1

Step 1 : word equation
Sodium Hydroxide +Sulphuric acid ---> Sodium sulphate + water

Step2 : write skeletal equation

NaOH + H2SO4 --> Na2SO4 + H2O

STEP 3: PREPARE a table with number of atoms on reactant side and product side
**********************************************
Element Reactant product
***********************************************
Na 1 2
S 1 1
O 5 5
H 3 2
************************************************

STEP 4: now multiply coefficient 2 to Na on reactant side
2NaOH + H2SO4 --> Na2SO4 + H2O

STEP 5: now multiply coefficient 2 to hydrogen on product side
2NaOH + H2SO4 --> Na2SO4 + 2H2O

Step6 : write physical states

2NaOH (aq) + H₂SO₄(aq) →Na₂SO₄(aq) + 2H₂O(1)
Hence equation is balanced
