What is electro-chemical series?
It is a vertical series in which different electrodes/substances are arranged in the increasing order of their REPVs with the standard Hydrogen Electrodes (SHE) / Normal Hydrogen Electrode (NHE) in the middle of the series which is assigned an REPV of 0 voltage.Note- REPV stands for Standard Reduction Electrode Potential Values.
What is electromotive series in terms of choosing the suitable electrode in setting up an electrochemical cell?
The electromotive series is a list of elements in order of their standard electrode potentials. When setting up an electrochemical cell, it is important to choose electrodes that have a large difference in standard electrode potential to maximize the cell's efficiency. This helps in determining which electrodes would make a suitable combination for generating the desired voltage in the cell.
What is the name for a reversible word?
A reversible word that reads the same forwards and backwards is called a palindrome.
What are the metal strips called that are placed in the copper compound solution during electrolysis?
The metal strips are called electrodes. The positive electrode is known as the anode, and the negative electrode is called the cathode. They are used to conduct electricity through the electrolyte solution to facilitate the electrolysis process.
Why are lyophillic called reversible colloids?
This is because evaporating the liquid the sol is destroyed.
How to separate hydrogen in water?
Hydrogen can be separated from water through a process called electrolysis. In this process, an electric current is passed through water, which causes the water molecules to split into hydrogen and oxygen gas. The hydrogen gas is then collected at one electrode, while oxygen gas is collected at the other electrode.
Is the dissociation of water reversible?
Yes, the dissociation of water is reversible. Water can dissociate into hydrogen ions (H) and hydroxide ions (OH-) through a process called ionization. These ions can recombine to form water molecules again in a reversible reaction.
How can you turn hydrogen into water and oxygen?
Hydrogen can be turned into water and oxygen through a chemical reaction called electrolysis. By passing an electric current through water (H2O), the hydrogen and oxygen atoms will separate, producing hydrogen gas (H2) at one electrode and oxygen gas (O2) at the other electrode.

What are the two gases used to produce electricity in fuel cells?
The two gases used to produce electricity in fuel cells are hydrogen (H2) as the fuel and oxygen (O2) as the oxidant. In a fuel cell, hydrogen is fed to the anode (negative electrode) and oxygen is supplied to the cathode (positive electrode), where they react to produce water, heat, and electricity through an electrochemical process called the oxidation-reduction reaction.
How does a water electrolyzer machine work to produce hydrogen gas?
A water electrolyzer machine works by using electricity to split water molecules into hydrogen and oxygen gas. This process, called electrolysis, occurs when an electric current passes through water, causing the water molecules to break apart. The hydrogen gas is collected at one electrode, while the oxygen gas is collected at the other electrode. This allows for the production of hydrogen gas as a clean and renewable energy source.

When setting up an electrochemical cell, it is important to choose electrodes that have a large difference in standard electrode potential to maximize the cell's efficiency.

What do you call the electrode connected to negative terminal of a cell?
The electrode connected to the negative terminal of a cell is called the cathode.
Is evaporation reversible change?
Yes it is reversible and the process is called condensation!

The metal strips are called electrodes. The positive electrode is known as the anode, and the negative electrode is called the cathode. They are used to conduct electricity through the electrolyte solution to facilitate the electrolysis process.
What is a 'reversible word' called?
A reversible word, or a word that is spelled the same forwards as it is backwards, is called a "palindrome." This term can also be applied to numbers or entire phrases.
