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.
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.
How do you get copper out of malachite?
In order to extract copper from malachite, the malachite must be heated to a high temperature. This produces a fine black powder (copper Oxide). The copper oxide is heated again to a more extreme temperature, this removes the oxygen, leaving metallic copper.
In chemical equilibrium what happens when Q is greater than K?
If Q > K, the reaction will move towards the reactants If Q < K, the reaction will move towards the products
What happens to the particles when you mix copper sulphate and iron?
Diffusion occurs - The particles of copper sulphate move between the particles iron because the particles are tiny and discrete.
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.
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.

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 do magnesium ions move to the negative electrode?

Why do positively charged ions move to the negative electrode?
The cause is the electrostatic attraction.
Gel electrophoresis separates DNA fragments on the basis of differences in their?
Length. DNA has a natural negative charge - and so will move towards the positive electrode. Larger fragments move more slowly than shorter ones - so the sizes of fragments can be determined.
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 paper clips move towards a maganet?
Paper Clips are made of usually made of steal or iron, which are magnetic materials, so they are attracted to magnets
Does DNA samples start at the negative or the black charge?
When DNA samples are run (i.e. in gel electrophoresis) they start at the negative end. This is because DNA carries a negative charge, and so will move towards the positive electrode. Therefore the DNA is placed at the other end (so it has room to move).
What happens to the pitch when you move towards a a speaker?
The pitch increases when you move towards the speaker.
