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.
In Science. A material that will not dissolve in another is known as insoluble. Wax will not dissolve in water, rocks will not disolve in alcohol, and so on. Caffiene is soluble in liquidâ¦ CO2 for example. Differential solubility is a very powerful technique in process chemistry and also in analysis. Teflon (polytetrafluorethylene) is a fairly inert substance, but starts to degrade above 200oC.
