Briefly explain why different products are obtained from the electrolysis of molten NaCl and the electrolysis of a dilute aqueous solution of NaCl. Explain why each of the following would or would not be a good buffer system. a. HCl/NaCl b. NH_4Cl/NH_3 c. HC_2H_3O_2/NH_3 e. HON...
NaCl does not conduct electricity in solid-state, however, it conducts in molten and solution form. Explain this phenomenon. Describe how the properties of the different types of elements (metals, nonmetals, metalloids) differ. Summarize the physical properties of ...
Electroplating is very similar to electrolysis (using electricity to split up a chemical solution), which is the reverse of the process by which batteries produce electric currents. All these things are examples of electrochemistry: chemical reactions caused by or producing electricity that give ...
Briefly explain why different products are obtained from the electrolysis of molten NaCl and the electrolysis of a dilute aqueous solution of NaCl. Describe and illustrate the electrolytic refining of Cu. What happens during electrolysis in a molar solution? What causes current to flow in an electro...
Why is the electrolysis of molten salts much easier to predict in terms of occurrence at the anode and cathode compared to the electrolysis of aqueous dissolved salts? Does potassium sulfate dissolved in water possess electrical conductivity? Explain. Explain the differenc...
Briefly explain why different products are obtained from the electrolysis of molten NaCl and the electrolysis of a dilute aqueous solution of NaCl. Explain why bubbling a solution with an inert gas such as argon or nitrogen causes deoxygenation of the solution? Describe how to prepare 1.0 L of ...
Describe how to standardize a solution of HCl. What happens in the electrolysis of calcium chloride? What happens when magnesium and solid ammonium chloride react? What happens to NaCl (salt) in water? If the concentration of HCl is doubled, what...
Explain the differences in conductivity of NaCl, HCl, and KOH. How do you explain how batteries work in terms of chemistry? Explain the way in which atoms are held together in a chemical compound. Define and explain the process of electrolysis in electrolytic cells. Describe the shielding effec...
Briefly explain why different products are obtained from the electrolysis of molten NaCl and the electrolysis of a dilute aqueous solution of NaCl. Why is a wire used to connect the electrodes in an electrochemical cell? Define the term "electrolysis" as used in the study of the effect of ele...
NaCl does not conduct electricity in solid-state, however, it conducts in molten and solution form. Explain this phenomenon. Why does the phase change take longer for solids than liquids? Describe what happens to ionic solids when they dissolve in water. Describe the bonding in metals and di...
