Acid-base atom balance

A neutral-formula representation used to practise coefficients; ionic descriptions require a separate treatment.

Equation

NaOH + H2SO4 -> Na2SO4 + H2O

Learning goal

Conservation of each element

Understanding this entry

A balanced equation establishes equal atom counts. It does not prove that a reaction will occur, identify hazards, describe equilibrium or provide a safe procedure. Use the reaction balancer to calculate and check the smallest positive integer coefficients.
