The balanced equation for the reaction between HNO3 and KOH is written as HNO3 + KOH = H2O + KNO3. HNO3 is the chemical formula representing nitric acid, KOH is the formula representing potassium hydroxide, H2O is the formula for water and KNO3 is the formula for potassium nitrate.
The process used to write a balanced equation is called stoichiometry. The stoichiometric coefficient is the number in front of each chemical in the equation, indicating the amount of the ion or molecule needed to create a balanced equation. The numbers within each chemical are typically written in subscript and refer to the number of atoms.
