# Charge Neutrality in Solids

Not what you're looking for?

What is the origin (e.g. physical, thermodynamic, etc.) of the charge neutrality requirement in solids? Why must solids have charge neutrality in the bulk, yet a surface can be charged? Why can't the bulk have a net charge?

##### Solution Summary

This solution deals with a very fundamental concept in physical chemistry, which is nicely elucidated with the help of pertinent reasons and one relevant equation.

Charge Neutrality in Solids
What is the origin (e.g. physical, thermodynamic, etc.) of the charge neutrality requirement in solids? Why must solids have charge neutrality in the bulk, yet a surface can be charged? Why can't the bulk have a net charge?

Good Question! Deals with some of the basic concepts in physical chemistry! We can explain this as follows:

Charge neutrality (e.g. ion-pairing) leads to more ...

• "Thankyou for the feedback. I have a few question though; With the first statistic about cost below... “According to Sigma-Aldrich catalog, cost of 1L octane is AUD \$ 392.00, whereas the cost of 1L ethanol is AUD \$196.00. Moreover, if ethanol is obtained from sugar industry as a by-product, it may cost even less. Source of oxygen is ambient atmosphere, so it costs nothing. So ethanol is much cheaper than petrol, in fact it is half-priced: AUD \$ (392-196) = \$ 196.” I didn't think it made sense because the cost of petrol per litre is normally a dollar something or even less than a dollar not a couple of hundred of dollars. For example, a statistic that I found in america was: "U.S. ethanol production costs are about \$1.20 per gallon of ethanol, or \$1.82 per gallon on a gasoline-equivalent basis." However, I was wondering whether you could find an Australian statistic. Also, you mentioned that H20 is not a greenhouse gas. However, in the combustion equations it is actually carbon dioxide and water vapour which are produced and they are both greenhouse gases. Finally, how do I calculate the energy efficiency of ethanol and petrol? "
