Answer:

Serum phosphorus is measured in milligrams of phosphorus per deciliter of blood (mg/dL). According to Mayo Medical Laboratories, a normal range for adults is generally 2.5 to 4.5 mg/dL. The normal range varies slightly depending on your ageThese symptoms include joint pain, muscle pain, and muscle weakness. People with high phosphorus levels can also experience itching and red eyes. Symptoms of more severe cases of high phosphorus may include severe constipation, nausea, vomiting, and diarrhea.

Exposure to sulphites has been reported to induce a range of adverse clinical effects in sensitive individuals, ranging from dermatitis, urticaria, flushing, hypotension, abdominal pain and diarrhoea to life-threatening anaphylactic and asthmatic reactions.

To determine the valency of the ionic molecule phosphorus tetraoxide (PO4, four atoms of oxygen and one atom phosphorus) you should multiply the total valency of the four oxygen atoms (valency 2) and subtract that from the valency of the phosphorus atom (valency 5), That reveals the valency of (PO4) is 3.The valency of an element is always a whole number, and some elements exhibit more than one valency, they have more than one valency such as sulphur (S) is divalent, tetravalent and hexavalent.

Hope it would help you!!!❤️
