Why do ionic compounds conduct electricity in an aqueous solution or when molten, but do not conduct electricity when in the solid-state? Explain why some electrolyte solutions are strongly conducting, whereas others are weakly conducting.

In an electrolyzer, you place a solution in a container and dip two terminals into it. You connect the terminals up to a battery or other power supply and pass electricity through the solution. Chemical reactions take place and the solution splits up into its atoms. If the solution you use...
Explain why the solution used for intravenous (IV) drips is a 0.9% (w/v) NaCl solution in H2O. Explain how you would prepare a 0.150 M solution of glucose in water. Explain how you would prepare a 1.135 m solution of KBr in water. Explain why glucose and palmitic acid differ in ...
Explain why aqueous solution of sodium chloride conducts electricity where as solid sodium chloride does not. Explain the difference between an electrolyte and a non-electrolyte. What is the role of sodium in living things? What are the possible effects if too much or too little...
This is an idealized version of the general problem of determining the resistance between two points in a volume of some material. Like, say, two electrode tips in a liquid electrolyte? Getting a mathematically exact solution in this situation requires integrating over an infinity of paths, even...
A combination of scattering and fluorescence measurements uncovered a two-step adsorption process that depends on the metal concentration in solution. SFG spectroscopy revealed a unique water structure related to this adsorption. A novel sub-ensemble analysis ofmolecular dynamics simulationsfurther clarified...
What are the main parts of a battery? The basic power unit inside a battery is called acell, and it consists of three main bits. There are twoelectrodes(electrical terminals) and a chemical called anelectrolytein between them. For our convenience and safety, these things are usually packedin...
