Read MoreThe Chemical Production of Phosphoric Acid. Phosphoric acid is needed in large quantities to be able to fill its many roles in industry, meaning that its production has to equal its large demand. This acid is most commonly created by two ways, with one being more energy intensive and more pure, while the other is faster and cheaper.
