It differs from intracellular fluid (fluid within the cells) in that it generally has a high concentration of sodium and low concentration of potassium, while intracellular fluid is high in potassium and low in sodium. The fluid is often secreted by cells to provide a constant environment for… Read More

What are Electrolytes?
Electrolysis is the process of passing an electric current through a substance in the molten or aqueous state thereby decomposing it. Glucose and urea do not dissociate in water because they have no electric charge. Therefore, these substances are called nonelectrolytes. The electrolyte is a compound which conducts electricity in the molten state or when dissolved in water. Recommended VideosElectrolytes ExplanationAn ionic compound for example, sodium chloride dissolved in water is called an electrolyte because it conducts electricity. Electrolytes are important body constituents because they,
Many biological compounds, for example, carbohydrates are not ionic and therefore have no electrical properties when dissolved in water. Important electrolytes other than sodium and chloride include potassium, calcium, bicarbonate and phosphate. 1. Major Electrolytes Outside the CellSodium and chloride, the major electrolytes in extracellular fluid, exert most of their influence outside the cell. Sodium concentration affects serum osmolality and extracellular fluid volume. Sodium also helps nerve and muscle cells interact. Chloride helps maintaining osmotic pressure. Gastric mucosal cells need chloride to produce hydrochloric acid, which breaks down food into absorbable components. Calcium and bicarbonate are two other electrolytes found in extracellular fluid. Calcium is the major cation involved in the structure and function of bones and teeth. Calcium is needed to
2. Major Electrolytes Inside the CellPotassium, phosphate and magnesium are among the most abundant electrolytes inside the cell. Potent potassium
Fundamental phosphorus The body contains phosphorus in the form of phosphate salts. Sometime the word phosphorus in the form of phosphate salts. Sometimes the words phosphorus and phosphate are used interchangeably. Phosphate is essential for energy metabolism. Combined with calcium, phosphate plays a key role in bone and tooth mineralization. It also helps maintain acid-base balance. Magnesium acts as a catalyst for enzyme reactions. It regulates neuromuscular contraction promotes normal functioning of the nervous and cardiovascular systems, and cardiovascular systems and aids in protein synthesis and sodium and potassium ion transportation. Understanding ElectrolytesElectrolytes help to regulate water distribution, govern acid base balance and transmit nerve impulses. They also contribute to energy generation and blood clotting. This table summarizes the functions of each of the body’s major electrolytes.
Electrochemical CellsElectrochemical cells are of three basic types. The electrolytic cell, the galvanic cell, and the concentration cell. All such cells are similar in that they have four basic components. These components are
Electrolyte MovementWhen cells die their contents spill into the extracellular area and upset the electrolyte balance. In this case, elevated levels of intracellular electrolytes are found in plasma. Although electrolytes are generally concentrated in a specific compartment, they aren’t confined to these areas. Like fluids, they move around trying to maintain balance and electroneutrality. Electrolyte BalanceFluid and output acid-base balance hormone secretion and normal cell function can influence electrolyte balance. Because electrolytes and individual imbalances in one electrolyte can affect balance in others. The body fluids contain a variety of dissolved chemicals that may be categorized as either nonelectrolytes or electrolytes. Nonelectrolytes are those compounds with covalent bonds that therefore do not dissociate when dissolved in water. Electrolytes are those compounds with at least one ionic bond that dissociate freely when dissolved in water. Even though electrolytes exist inside and outside only the levels outside the cell in the bloodstream are measured. Although serum levels remain fairly stable throughout a person’s life span, understanding which levels are normal and which are abnormal is critical to decide quickly and appropriately to a patient’s electrolyte imbalance. Frequently Asked Questions on ElectrolytesAll electrolytes are sodium, calcium, potassium, chlorine, phosphate, and magnesium; You get them from the food you consume and your drinking fluids. Electrolyte levels can become
too small or too high in your body. This can happen when the body changes its amount of water. Electrolytes are compounds in body fluids that make up electrically charged particles (ions). These ions hold the required electrical energy for
many functions including muscle contractions and nerve impulse transmission. Numerous body functions depend on electrolytes. Electrolytes are found in the human body, and the electrolyte balance in our bodies is necessary for our cells and our
organs to function normally. Common electrolytes tested by blood-testing physicians include sodium, potassium, chloride, and bicarbonate. Is Salt an electrolyte?Placing a salt in a liquid (such as water) often contributes to an electrolyte solution, as the salt components dissociate in a process called liquid. Electrolytes can also be smelted salts. Molten sodium chloride, for example, is a liquid that can conduct electricity. Is water an electrolyte?Simple water, which has a very low ion content, can’t conduct electricity. When a solvent dissociates to form ions in water, it is called an electrolyte, since the solution is a strong electrical conductor. Is sugar a Nonelectrolyte?Glucose, or C6H12O6, is a typical example of a nonelectrolyte Glucose (sugar) dissolves readily in water, but because it does not dissociate in solution into ions, it is called a nonelectrolyte; glucose-containing solutions, therefore, do not conduct electricity. “Nonelectrolyte” says. Which electrolytes are found in the greatest amounts in the intracellular fluid?The most abundant electrolyte in intracellular fluid is potassium. Intracellular fluids are crucial to the body's functioning. In fact, intracellular fluid accounts for 60% of the volume of body fluids and 40% of a person's total body weight! Extracellular fluids (ECF) are fluids found outside of cells.
Which is the largest component of intracellular fluid?The main ICF electrolyte is potassium. Therefore, when potassium levels decrease in the cell, osmotic pressure is lost and water moves out of the cell. When too much water is lost in the ICF, the cell can shrink, which causes a loss of cellular function.
Which ion is found in the highest abundance within the intracellular fluid?As the most abundant cation in intracellular fluid, potassium plays an important role in a variety of cell functions.
What is the major electrolyte in extracellular fluid?Sodium, which is an osmotically active cation, is one of the most important electrolytes in the extracellular fluid. It is responsible for maintaining the extracellular fluid volume, and also for regulation of the membrane potential of cells.
