An electrolyte is a substance that, when dissolved in an aqueous medium produces ions. The electrolyte in solution breaks into cations and anions, which spread evenly throughout the solvent. Answer and Explanat
Explain why some electrolyte solutions are strongly conducting, whereas others are weakly conducting. Explain about how to measure electromotive force (EMF) of a sample solution by using an Ion-Selective Electrode (ISE). Describe what is inside the alkaline dry cell once it is fully discharged....
Chemical elements differ in their ability to pull electrons toward them—or give them up to other elements that pull on them more. We call this tendencyelectronegativity. Stick two different metals into an electrolyte, then connect them through an outer circuit, and you get a tug-of-war going...
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...
The electrolysis of water is often done by passing a current through a dilute solution of sulfuric acid. What is the function of the sulfuric acid? Explain how fission can be used to generate electricity. Explain chemically how an electrolytic cell works for both the hydrolysis of water and el...
What do the terms hydrophobic and hydrophilic mean? Explain how you would prepare a 0.150 M solution of glucose in water. Define an electrolyte. The given model is that of an aldohexose. Is this a D or L sugar? Explain. Is C2H5OH an electrolyte or a non-electrolyte? Explain. Define an...
For example, brine solution is a good electrolyte, while pure distilled water is not an electrolyte. The strength of an electrolyte has consequences in many of its chemical properties, for example, strong electrolytes manifest a greater degree ...
A cell is transferred from an isotonic solution to a hypotonic solution. What happens to the cell? 1. Explain why water is such a good solvent for so many different solutes? 2. Why should solutes be added to water rather than water added to solutes ? Explain what di...
What makes an electrolyte weak or non-electrolyte? Explain. Why is water a poor conductor of electricity? Why does a solution of sodium chloride in water conduct an electric current? Is silver a conductor or a semiconductor? Explain. What does the conductivity of a material depend on?...
Is lead metal classified as a pure substance (element or compound) or a mixture? Explain. How does electrolyte conductivity affect corrosion rates? Why would HF have a lower electrical conductivity than NaCl? Electroplating is performed by using a source of direct current. ...
