Evans KJ, Neurologic signs of hypokalemia include generalized weakness and decreased deep tendon reflexes.Repeat measurement of serum potassium can help identify pseudohyperkalemia, which is common and typically results from potassium moving out of cells during or after sample collection.ECG should be considered if the potassium level is greater than 6 mEq per L; if there are symptoms of hyperkalemia; if there is suspicion of rapid-onset hyperkalemia; or among patients with underlying kidney disease, heart disease, or cirrhosis who have a new case of hyperkalemia. Onyanga-Omara F, You're right, lithium carbonate does "end" in #"CO"_3#, but a more accurate way of putting it would be that it contains the carbonate anion, #"CO"_3^(2-)#.. The lower melting point of the mixture (400–420 °C, or 750–790 °F) compared with that of pure lithium chloride (610 °C, or 1,130 °F) permits lower-temperature operation of the electrolysis.
