When asked what causes electrolyte solutions to conduct electricity a student responds that it is due to the movement of electrons through the solution Is the student correct?
NO!!! The ions move through the solution. The ions migrate to their oppositely charged electrodes. Whereupon the ions and the given metal of the electrode 'swop' electrons. The electrons the move through the circulating wire to the other electrode as electricity. A positively charged ion will move to the negative electrode. Whereupon, electron(s) combine to the ion , which is deposited on the electrode. The electrode will gain mass. A negatively charged ion will move to the positively charged electrode. Whereupon it loses its electron into the electrode. which flows from the electrode through the wire to the other electrode. to complete the circuit.
Why do positively charged ions move to the negative electrode?
The cause is the electrostatic attraction.
Why is copper pliable but copper sulfate not pliable?
Copper is a simple metal. It is held togeth by metallic bonds. In this setup, positively charged copper ions sit in a mutually shared "pool" of electrons. The ions are essentially held together by their attraction to these electrons. Since these electrons are free to move throughout the metal, the copper is not limited to any rigid form. Copper sulfate is a salt, consisting of positively charged copper ions and negatively charged sulfate ions. This forms a definite crystal lattice, with the ions arranged into a rigid, repeating structure. When you apply enough force to the crystal, you will force the positive and negative ions out of alignment along a portion of the structure. When this happens the bonds between the ions, which depended on this alignment, break and the crystal fractures or cleaves.
In a wet cell electrons move from the negative electrode to the positive electrode?
A wet cell refers to a primary electric cell wherein the electrolyte is a liquid. It is true that in a wet cell, electrons move from the negative electrode to the positive electrode.
How does diffusion take place when copper sulphate crystals dissolve?
CuSO4 ions move from crystal to water ie from high concentration to low conc. area while H2O molecule also move into crystal thus copper sulphate is dissolved in water .
What is electrolycis process?
The ability of getting split into ions is known as electrolyte. So through electrolyte current can be passed as these ions would make possibility for the easy of current. This process is called electrolysis. The ions those positive would move towards the electrode which has been connected to negative polarity of the battery. Hence the electrode thus connected is known as cathode and the positive ions moving towards the cathode are known as cations. Same way negative ions are called as anions as they move towards the anode. With this electrolysis process fine plating of gold on copper is possible and this is known as gold covering. Same way pure metals can be separated from its ore.

Why is copper used for the electrodes?
Because sulphate ions move towards anode (copper) the copper of anode donates 2 electrons to external circuit and becomes +2 ions and moves to the solution so copper anode continuously dissolves in solution.
Why do positively charged ions move to the negative electrode?
The cause is the electrostatic attraction.
What is the opposite to a cathode?
A cathode is an electrode through which electrical current exits a polarized electrical device. Its opposite is the anode, through which electrical current enters the electrical device. Positively charged ions, called cations, move towards the cathode, while negatively charged ions, called anions, move towards the anode.
why ionic solid don't conduct current in solid state?
Ionic substances conduct electricity through the migration of ions. Positive ions move toward the negative electrode (cathode), and negative ions move toward the positive electrode (anode). In a solid there is no migration (movement) because the ions are locked together in a crystal lattice, the solid form.
In the process of electrolysis current can flow through liquid why?
Ions in the liquid will respond to an applied voltage, and as long as these ions are mobile within the liquid, they can support current flow. Salt in water is a good example. In solution, salt becomes sodium and chlorine ions in the water. Apply a voltage across (or through) the salt water, and the mobile ions will carry the electric charge which is current flow.
Why does water conduct electricity?
Saltwater conducts electricity because of the salt that is in thewater. What happens is when an electrical current is ran through the water then the ions from the dissolved salt splits into positive and negative ions and therefor it is conducting electricityConductivity of water is due to the formation of ion i.e H(+) and OH(-) ions.when the electrode is dissolved in water and given some potential .The supplied energy is used for the splitting of ion .Then +ve and -ve ions move towards respective electrode and hence due to the movement of ion it conducts electricity.

Why molten copper chloride conduct electricity?
As copper and chlorine are bonded by ionic bonding , they are placed in a crystal lattice and there is no free moving ions to conduct electricity at the solid state. In molten state, the ions are free to move about.
