What else can I help you with?
What happens to the mass of the metal anode as the cell continues to operate?
It depends on the specifics of the cell, but in most simple galvanic cells, the anode slowly dissolves into solution.
Why did the anode become thinner after the electroplating of spoon with silver?
The anode became thinner after the electroplating of the spoon with silver because silver ions from the anode are released into the solution during the electroplating process. As these ions are deposited onto the spoon's surface, they reduce the mass of the anode, causing it to lose material. This process is essential for maintaining the flow of silver ions, ensuring effective plating of the spoon. Thus, the anode directly contributes to the deposition of silver onto the object being plated.
Which electrode in the anode is galvanic cell?
Zinc is the anode.
What kind of sign does anode has?
An anode is positive, Cathode is negative. As such, an anode would usually be denoted as + If that is what you meant.
The anode in an electrochemical cell has this charge?
The Anode in electrochemical cell has negative charge (-ve).
What are the cathode and anode in a fuel cell made from?
The cathode in a fuel cell is typically made from a material like platinum, which serves as a catalyst for the oxygen reduction reaction. The anode is usually made from a material like nickel, which helps facilitate the oxidation of the fuel.
What is an anode made from?
Anode is the negative terminal of a battery. It is made of Tungsten which is the same metal used in the filaments of bulbs.
What happens to the mass of the metal anode as the cell continues to operate?
It depends on the specifics of the cell, but in most simple galvanic cells, the anode slowly dissolves into solution.
What is the gas liberated at anode in the manufacture of caustic soda using nelson cell?
The raw material for the manufacturing of caustic soda is sodium chloride so gas liberated at anode is chlorine.
What types of anode?
the two types of anode is stationary anode and rotating anode
Can you call forward bias voltage as positive voltage?
it is not necessary that always positive voltage should act as a forward bias voltage , it is the potential difference between cathode and anode that makes it forward or reverse biased .it the anode(p- doped material) positive with respect to cathode(n- doped material) --> forward biasedit the anode(p- doped material) negative with respect to cathode(n- doped material) --> reverse biasedex.anode - 5v cathode - 3vanode - 1v cathode - -2vboth the examples are forward biased.
Anode current in an thyristor is made up of?
Holes and electrons
What is always true during the operation of a voltaic cell?
During the operation of a voltaic cell, electrons flow from the anode to the cathode through an external circuit, generating an electric current. The anode undergoes oxidation (loses electrons), while the cathode undergoes reduction (gains electrons). This process is driven by a redox reaction occurring within the cell.
What is reversed conditioning?
The cathode must be made more positive with respect to the anode.
Why did the anode become thinner after the electroplating of spoon with silver?
The anode became thinner after the electroplating of the spoon with silver because silver ions from the anode are released into the solution during the electroplating process.

Can the water heater operate without a sacrafical annode?
Water heaters can operate without an anode rod. If tank is not made of steel, then no anode rod is present. If tank is made from steel or glass-lined steel, then anode rod is necessary for long life of tank. Without anode rod, water will rust tank causing leaks and possible failure where tank bursts open and floods house until water is turned off. Anode rods are made of lower noble metals than steel water heater tank. When the two metals are connected together, water reacts with lower noble metal first, so the water dissolves anode rod instead of rusting tank. Anode rods should be checked every two-four years, more frequently when water is softened. Factory-made, gas and electric, steel water heaters come with one or two anode rods installed. Tanks with longer warranties generally have two anode rods. Check manual for specifics. Adding a second anode rod can prolong life of water heater. Ship hulls and propellers, and steel bridges, and other structures that come in contact with water also have anode rods.
What is reverse bias condition?
The cathode must be made more positive with respect to the anode.
