phosphorus villain
The oxygen and the phosphorus react to form phosphorus Pentoxy.
Phosphorous (P) and oxygen (O ^) react to form phosphorous dioxide (P ^O ^). The chemical equation is 4P +5O ^= ignition = 4P ^O ^. The reaction phenomenon was intense combustion, emitting white light, releasing heat, and producing a large amount of white smoke. The white smoke here was the solid particles of phosphorus Pentoxy. In the experiment of measuring the oxygen content in the air by burning red phosphorus, in order to consume the oxygen in the air, the red phosphorus needed to be excessive, and charcoal, sulfur, and iron wire could not be used to replace the red phosphorus for the experiment.

Determination of Phosphorus in Flame Reaction
The flame reaction test for the determination of the potassium ion mainly had the following steps: First, the platinum wire was dipped in concentrated sulfuric acid and burned on a colorless flame until it was colorless. Then, the sample was dipped in the colorless flame and burned. Then, the color of the flame was observed through the blue Cobalt Glass. If the flame was purple, it meant that the sample contained the potassium ion. Otherwise, it did not. After the experiment, the platinum wire was dipped in concentrated sulfuric acid and burned until it was colorless. In the flame reaction, because the yellow color of the Na flame might cover up the color of the K flame, it had to be observed with blue Cobalt Glass. This method originated from Bunsen's experiment.

Reaction of Red Phosphorus and Isopropvl
The reaction of red phosphorus with potassium alcohol was a substitution reaction, and the reaction formula was CH3- CH(SH) -CH3 +I2(P)→ CH3-CHI-CH3 +HOI, where P13 was the catalyst. In addition, the red phosphorus was mixed evenly with the alcohol, placed in a ball mill tank, and ball-grinded under a protective atmosphere, then washed with alcohol and dried to obtain the ball-grinded red phosphorus.

The reason for the excessive phosphorus in the big rivers
The reason for the excessive phosphorus in " Big River 3 " was that two technical backbones violated the regulations to purify and increase the amount, privately changed the formula of the original drug, and signed on behalf of Manager Cao, resulting in the serious excessive phosphorus. In addition, it was also possible that factors such as aging equipment and agricultural non-point source pollution caused the phosphorus to exceed the standard. However, the investigation team had yet to give a final conclusion. More evidence was needed to find the real source of the poison. Therefore, it could be said that there were many reasons for the excessive phosphorus, including human factors and environmental factors.

Can azalea flowers be watered with monocratic phosphorus?
Azalea flowers could be watered with monocratic phosphorus, which was mainly used to promote flowering and differentiation. However, when using it, one had to pay attention to the concentration control, the soil condition, the weather conditions, and other factors. Otherwise, it might not be effective or cause fertilizer damage, causing the seedlings to burn.
