Question
How do you prepare a 10% potassium iodide solution using 1 gram of potassium iodide? What are the symptoms of overdose?
Answer
To prepare a 10% potassium iodide solution, simply dissolve 1 gram of potassium iodide in 100 milliliters of solvent. Chronic overuse may lead to symptoms such as oral and throat burning, drooling, metallic taste and gingival pain, abdominal discomfort, severe headache, which are indicative of iodine poisoning. It may also cause hyperkalemia, presenting as confusion, arrhythmias, numbness or tingling in the hands and feet, and weakness or heaviness in the lower limbs. Additionally, allergic reactions, joint pain, increased eosinophils, and enlarged lymph nodes may occur.
