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.
Solids can be found in nature in a dissolved form. Salts that dissolve in water break into positively and negatively charged ions. Conductivity is the ability of water to conduct an electrical current, and the dissolved ions are the conductors.The major positively charged ions are sodium, (Na +) calcium (Ca +2), potassium (K +) and magnesium (Mg +2).ecause dissolved ions increase salinity as well as conductivity, the two measures are related. The salts in sea water are primarily sodium chloride (NaCl). However, other saline waters, such as Mono Lake, owe their high salinity to a combination of dissolved ions including sodium, chloride, carbonate and sulfate.
