This reaction is reversible and equilibrium point is Following steps are important in calculation of pH of ammonia solution. Nitric acid is heavier than water, so if you have a solution with just nitric acid and water (and nothing else), and you know the temperature (because water expands with heat, affecting the specific gravity), it is possible to correlate the hydrometer's specific gravity reading to the nitric acid concentration via a simple table. But this only works for initial makeup. A.
