They can, actually. That's what the whole dialysis method is based on.

Sodium ions are too small to be effectively restricted by the pores present in dialysis tubing. The pores in the tubing are designed to allow passage of molecules based on size, charge, and shape. Due to their small size, sodium ions are not hindered by the pores and can freely move across the membrane.

Why cant carbon be used to extract sodium from its ore?

Carbon cannot be used to extract sodium from its ore because sodium is more reactive than carbon. When carbon reacts with sodium ore, carbon will preferentially react with oxygen in the ore to form carbon dioxide rather than extracting sodium from the ore. Therefore, other methods such as electrolysis are used to extract sodium from its ore.


What is the equation for the decomposition of sodium hydroxide?

The dissociation reaction for sodium hydroxide in water is as follows: NaOH(s) ---> Na+(aq) + OH-(aq)


What is a shiny black solid or in purple gas and its found in table salt?

table salt is NaCl (sodium chloride) so its either sodium or chlorine chlorine is a green gas so it cant be that sodium is a light silvery solid so it cant be that the question doesn't seem to make much sense


Can sodium and potassium combine to form a covalent bond?

Sodium and potassium are both metals that typically form ionic bonds with nonmetals. Due to their low electronegativity, they are unlikely to form a covalent bond with each other as it would require sharing of electrons, which is not favorable for metals.


Is sodium hydrogencarbonate and citric acid an exothermic or endothermic reaction?

Yes, the reaction of sodium with water is highly exothermic.When sodium is dropped in water, a shiny grobule of sodium is formed which darts around on the surface of water.Hydrogen is liberated in the process which catches fire immediately and burns with a pale blue flame.NaOH is also formed in the process. EQUATION: 2Na+water -> NaOH + H2

Why do the RPMs fluctuate on their own without hitting the accelerator?

I am having a similar problem with my 95' w/351. Mine fluctuates by about 300 rpm's and is fairly consistant every 3-5 seconds. I've been told that it is a vacuum leak, however, I've replaced just about all of my vacuum lines. You cant buy the factory hard plastic tubing, so I fabricated my own out of aluminum tubing and a cheap tubing bender. The aluminum tubing is readily available from hobby stores and is fairly inexpensive. Hope this helps you out. I cant find anymore vacuum leaks on mine, but it still fluctuates. Jon
