Why does NaCl (aq) conduct electricity but NaCl (s) does not. read more. ii) in the electroplating of an article with silver, the electrolyte sodium argento-cyanide solution is preferred over silver nitrate solution. . iii) Although copper is a good conductor of electricity, it is a non-electrolyte. On heating sodium chloride melts and it becomes liquid. Electrons are shown as e–. This means it yields ions in solution. How can sodium be obtained from sodium chloride? [O=16].

Sulphuric acid on sulphur. Its outermost shell or energy level has only one electron. If 100cm3 of ammonia is used. (Note: for the same reason an aqueous solution of NaCl conducts electricity as NaCl ionizes to give Na+ and Cl- ions) (i) B -Non-volatile acid(ii) A-Typical acid property(iii) C- Oxidizing agent, 232, Block C-3, Janakpuri, New Delhi, State what would you observe when:i) Washing soda Crystal are exposed to the atmosphere.ii) The salt ferric chloride is exposed to the atmosphere.
Salt solution such as sodium chloride (NaCl) conducts an electric current because it has ions in it that have the freedom to move about in solution. In order to conduct electricity a substance must have charge particles, such as electrons and ions, that are free to move freely through it. In solid form bond between these two is very strong. However, sodium is too reactive for this to happen so hydrogen is given off instead. Most ionic compounds conduct electricity either in their molten or solution forms but not in their solid forms. Why is NaCl called sodium chloride, not chloride sodium? You might have expected sodium metal to be deposited at the negative electrode. Give a reason why: i) Sodium chloride will conduct electricity only in fused or aqueous solution state. But in water the ions become free and move randomly. In the solid state, ionic compounds such as sodium chloride have their ions fixed in position and therefore these ions cannot move so solid ionic compounds cannot conduct electricity. Each sodium atom is surrounded by eight other sodium atoms, each of which has one electron in its outermost energy level. Sodium Chloride solution (dissolved in water) conducts electricity, and molten Sodium Chloride conducts electricty, but dry crystal Sodium Chloride does not conduct electricity. But in water the ions become free and move randomly. [Atomic No. What happens when you mix barium chloride and sodium chloride? Sodium Chloride is an ionic compound which consists of Sodium ion and Chloride ion. Read about our approach to external linking. Why is sodium chloride a good conductor of electricity? The close proximity of the atoms in solid sodium leads to the sharing of space between the atoms and therefore the sharing of the outermost electrons. This is because in its molten or solution state, sodium chloride is dissociated into its component negative and positive ions. The equation 4NH3 +5O2 ---> 4NO +6H2O, represents the catalytic oxidation of ammonia. i) Name the solution used to react with Bauxite as a first step in obtaining pure aluminium oxide, in the Bayer's process.ii) Write the equation for the reaction where the aluminium oxide for the electrolytic extraction of aluminium is obtained by heating aluminium hydroxide.iii) Name the compound added to pure alumina to lower the fusion temperature during the electrolytic reduction of aluminaiv) Write the equation for the reaction that occurs at the cathode during the extraction of aluminium by electrolysis.v) Explain why it is preferable to use a number of graphite electrodes as anode instead of a single electrode, during the above electrolysis.
