Potassium is one of the body’s major ions. Nearly 98% of the body’s potassium is intracellular. The ratio of intracellular to extracellular potassium is important in determining the cellular membrane potential. Small changes in the extracellular potassium level can have profound effects on the function of the cardiovascular and neuromuscular systems. The kidney determines potassium homeostasis‚ and excess potassium is excreted in the urine. The reference range for serum potassium level is 3

Other function include: working with potassium and calcium to maintain neuromuscular irritability for conduction of nerve impulses‚ regulation of acid-base balance (through sodium bicarbonate and sodium phosphate)‚ participation in cellular chemical reactions and membrane transport. * Potassium: K+ 3.5-5.0 mmol/L: Potassium maintains the osmotic balance of the ICF space. Potassium is the major intracellular electrolyte and contributes to many important

2H+(aq) + 2I- (aq) Since iodine dissolves slightly in water‚ ascorbic acid cannot be titrated directly by a standard solution of iodine. Therefore‚ back titration technique is employed in this experiment. In an acidic medium‚ potassium iodate(V) reacts with potassium iodide to produce iodine in situ. KIO3 (aq) + 5KI (aq) + 3H2SO4 (aq) 3I2 (aq) + 3H2O (l) + 3K2SO4 (aq) The iodine produced reacts with ascorbic acid immediately. Then‚ the iodine left is titrated by a standard solution of

Sodium and Potassium function as electrolytes in which they help balance the amount of fluids in the body and transmit electrical nerve impulses (What Role Does Potassium Play in Muscle Contraction?). The majority of the potassium in the body can be found in the muscle tissue‚ most of which reside in the cell membrane while sodium remains in the fluid around the cell (What Role Does Potassium Play in Muscle Contraction?). The balance sodium and potassium of makes an electrical and

acetychloine is removed from the receptors on the cells. This in turn causes the receptor mediated Na+ leak channels to close. Voltage gated potassium leak channels open as a result. As K+ ions begin coming into the cytoplasm to repolarize. When the membrane potential reaches a specific level‚ the voltage gated potassium leak channels close as well. The sodium potassium pump works throughtout this process‚ by pumping Na+ ions out and K+ ions into the cells (using ATP‚ by a process called active transport)
