The Reaction of Sodium in Water - ChemTalk
网页When you mix sodium with polar water, protons, and hydroxyl ions, what happens? The loosely held electron from the sodium will want to react with the single proton it can find. The electrons from sodium combine with hydrogen ions which happens as more neutral water molecules dissociate to provide free protons; this takes about 13.6 eV of energy.
网页The sodium ion is ubiquitous in water. Most water supplies contain less than 20 mg of sodium per litre, but in some countries levels can exceed 250 mg/litre. Saline intrusion, mineral deposits, seawater spray, sewage effluents, and salt used in road de-icing can all contribute significant quantities of sodium to water.

网页2019年9月11日 · Structural, thermodynamic, and vibrational characteristics of water clusters up to six water molecules incorporating a single sodium ion [Na + (H 2 O) n (n = 1–6)] are calculated using a comprehensive genetic algorithm combined with density functional theory on global search, followed by high-level ab initio calculation.
Sodium Homeostasis, a Balance Necessary for Life - PMC
网页2023年1月12日 · Maintenance of this ion within appropriate levels (Na balance) is not only an adaptive process necessary for survival but also an essential component of hydromineral homeostasis (Na and fluid balances). Na is the primary cation in extracellular fluid (ECF) and, along with associated anions, constitutes 90% of ECF osmolality [4,5].
The hydration number of Na+ in liquid water - ScienceDirect
网页2001年7月1日 · In the top panel, the Na + ion has five (5) inner shell water molecule neighbors. The bottom panel shows the four-coordinate structure produced 70 fs later. The bonds identify water oxygen atoms within 3.1 Å of the Na + ion. The hydrogen, sodium, and oxygen atoms are shown as open, blue and red circles, respectively.

11.4: Hydration of Ions - Chemistry LibreTexts
网页2023年7月16日 · This process, in which either a positive or a negative ion attracts water molecules to its immediate vicinity, is called hydration. When water molecules move closer to ions under the influence of their mutual attraction, there is a net lowering of the potential energy of the microscopic particles.
