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.
Substances that exist in solution almost completely as ions are called strong electrolytes. Substances that do not form ions when they dissolve in water are called non-electrolytes. And example of a non-electrolyte is sugar. Sugar will readily dissolve in water but doesn't form cations and anions in solution. That is, there are no charge carriers formed.
