The method of making phosphoric acid from phosphoric acid
If you want to make phosphoric acid from phosphoric acid, it is not easy, so you must be clear and careful.

Prepare all things first, phosphoric acid, zinc powder, and sulfuric acid are essential. Zinc powder can participate in the reaction due to its activity; sulfuric acid is liquid-regulating and helps to respond smoothly.

In the stabilizer, put an appropriate amount of phosphoric acid, slowly add sulfuric acid, and stir well. The amount of sulfuric acid is determined by the quality of phosphoric acid. Do not overdo it, causing chaos.

When it is finished, it gradually enters the zinc powder. When the zinc powder enters the liquid, it will melt immediately, and gas will escape. This is hydrogen. When the temperature of the container rises, it must be carefully controlled, so as not to overheat, so as to prevent accidents.

Wait for the reaction to slow down, and the things in the liquid will gradually melt. Hypophosphoric acid is born in the middle, and then mixed with all things. To obtain pure hypophosphoric acid, it is even more necessary to separate it.

Use the method of distillation to remove its impurities. The boiling point of hypophosphoric acid is specific, and the temperature control is appropriate, so that the hypophosphoric acid can be gasified out, re-condensed into a liquid, and collected in other vessels.

Considering that the impurities in it may not be purified, it can be purified by the method of crystallization. Place the liquid in the adapter, lower its temperature, hypophosphoric acid precipitates into Re-dissolve crystals in water to obtain pure hypophosphoric acid solution.

To make hypophosphoric acid in phosphoric acid, all steps must be careful and clear methods can be obtained.
