Balance the equation for the reaction of sodium hydroxide with sulphuric acid.
H2SO4 + NaOH --> Na2SO4 + H2OWrite out all the elements involved, and how many times they appear on each side.H 3:2,S 1:1,O 5:5,Na 1:2.Start by making the number of sodiums the same on both sides by putting a 2 in front of NaOH:H2SO4 + 2NaOH --> Na2SO4 + H2O.H 4:2,S 1:1,O 6:5,Na 2:2.Then make the number of hydrogens equal on both sides by putting a 2 in front of H2O:H2SO4 + 2NaOH --> Na2SO4 + 2H2O.This makes the number of oxygens equal as well, so the equation has now been balanced.
