Vitamin B12 and the Elderly. Vitamin B12 and the elderly is especially important because as we age, our ability to absorb nutrients from food declines. This condition is called atrophic gastritis and is one of the most common causes for vitamin B12 deficiency among the elderly.
Best Answer: A nonelectrolyte is a substance that doesn't split up into ions when dissolved into solution. LiF is an ionic compound that is soluble in water, completely splitting up into ions. HCl is a strong acid, completely splitting up into ions when dissolved in water. Acetic acid is a weak acid. When dissolved in water, a small percentage of it splits into ions, so it still is an electrolyte. Sucrose does NOT split up into ions when dissolved in water so it is a nonelectrolyte.
The solubility of ionic salts in water is generally determined by the degree of solvation of the ions by water molecules. Such coordination complexes occur by water donating spare electrons on the oxygen atom to the ion.aking a saline water solution by dissolving table salt (NaCl) in water. The salt is the solute and the water the solvent. Gold, formerly dissolved in crystal of pyrite, is left behind after the cubic crystal of pyrite dissolved away. Note a corner of the former cube seen in center of rock.
