Disodium Hydrogen Phosphate (1.53g), commonly referred to as Disodium Hydrogen, is a chemical compound that is used in a variety of applications, especially in medicine and laboratory settings. In medicinal formulations, it is typically used as a buffering agent, helping to maintain the pH balance of the solution. It is also used in intravenous fluids and oral rehydration salts to restore electrolyte balance in patients, particularly in cases of dehydration or electrolyte imbalances.

Disodium hydrogen phosphate helps regulate the acidity or alkalinity (pH) of solutions, ensuring that they remain within a safe range for the body. It can be involved in the treatment of conditions like metabolic acidosis or for maintaining proper pH in the body. When used in combination with other compounds, it can assist in the absorption of certain nutrients or help reduce the risk of side effects by controlling the acidity of the solution.
