This document summarizes the electrolytic production of hydrogen from water. Water molecules are introduced to positive and negative electrodes where an electrical current provides electrons. This introduces electrons to the water molecules, filling the electron clouds of the atoms and breaking the covalent bonds between hydrogen and oxygen. The hydrogen atoms separate and concentrate around the negative electrode where they can be harvested as fuel, while oxygen atoms separate around the positive electrode.

Saman Tanoli will present on electrochemical cells. The presentation will define electrochemical cells, describe their components and types, including voltaic/galvanic cells and electrolytic cells. It will explain the differences between galvanic and electrolytic cells and provide examples of their applications. Voltaic cells generate electricity from spontaneous redox reactions, while electrolytic cells use electricity to drive non-spontaneous reactions. Common examples are batteries and electroplating/electrorefining of metals.Electrochemical cell

This document discusses electrochemical cells. It defines an electrochemical cell as a device that can generate electrical energy from chemical reactions or use electrical energy to drive chemical reactions. There are two main types of electrochemical cells: galvanic/voltaic cells which convert chemical energy to electrical energy, and electrolytic cells which convert electrical energy to chemical energy.
A galvanic cell consists of two half-cells with different metal electrodes immersed in electrolyte solutions, connected by a salt bridge or porous membrane. Chemical reactions at the electrodes produce a spontaneous flow of electrons through an external circuit. For example, in a Daniell cell zinc undergoes oxidation and copper undergoes reduction. The overall cell reaction is Zn + CuDiffrences

The document discusses several key chemistry concepts including:
1. Electrolytes and non-electrolytes, where electrolytes conduct electricity in solution and form ions, while non-electrolytes do not conduct electricity or form ions.
2. Acids and bases, where acids donate hydrogen ions in solution and bases donate hydroxide ions, changing indicator colors.
3. Ionic and covalent bonds, where ionic bonds involve a full transfer of electrons between atoms and covalent bonds involve shared electron pairs between atoms.
4. The differences between ionic compounds, covalent compounds, and their properties such as melting points.Electrochemical cells 1

This document discusses electrochemical cells, which can generate electrical energy from chemical reactions (voltaic cells) or use electrical energy to cause chemical reactions (electrolytic cells). Voltaic cells rely on spontaneous redox reactions to produce electricity, as in batteries. Electrolytic cells require an external electrical input to drive non-spontaneous redox reactions, such as in water electrolysis or electroplating. The document explains the basic concepts and applications of both voltaic and electrolytic cells.Ch19 notes electrochem complete 041913

This document provides an overview of key concepts in electrochemistry including:
- Voltaic (galvanic) cells consist of two half-cells that generate a spontaneous electron flow. A salt bridge and connector are needed.
- Standard reduction potentials (E属) are assigned to half-reactions and used to predict spontaneity of redox reactions. The half-cell with a more negative E属 acts as the anode.
- The standard hydrogen electrode serves as a reference point. Cell potential (E属cell) is calculated as the cathode potential minus the anode potential.
- The Nernst equation describes how cell potential varies with non-standard concentrations. Concentration cells exploit this.

Dr. K. Rajender Reddy gave a lecture on electrochemistry that covered several topics:
1) Electrode potential is the tendency of a metal to lose or gain electrons when in contact with a solution of its own salt. Zn undergoes oxidation in ZnSO4 by releasing electrons, while Cu undergoes reduction in CuSO4 as copper ions are deposited.
2) The standard electrode potential is measured at 25属C with a 1M electrolyte concentration and represents the potential of an oxidation or reduction reaction.
3) The electrochemical series arranges electrodes in order of increasing standard reduction potentials, ranging from the strongest reducing agent Li to the strongest oxidizing agent F.Simple voltaic cell and Chemical Cells

A simple cell consists of two different metal electrodes immersed in an electrolyte. Electrons flow from the more reactive metal to the less reactive one through the external circuit, producing an electric current. Batteries can contain one or more simple cells connected in series to increase voltage.

Lead acid batteries are commonly used in vehicles and for backup power. They contain lead plates separated by electrolyte and produce 12 volts through a chemical reaction. During discharge, lead plates react with sulfuric acid electrolyte to produce electricity, becoming more similar. Recharging reverses the reaction by applying current to reform lead and lead dioxide plates. Lead acid batteries require little maintenance but can have issues if electrolyte levels drop or plates corrode over time.Types of Electrochemical Cells

This document discusses reference electrodes, which maintain a constant potential regardless of current. It describes how reference electrodes establish a reference point for measuring potential in voltammetric methods. An ideal reference electrode uses stable, well-defined half-cell components. The standard hydrogen electrode (SHE) is described as the reference, but it is impractical, so saturated calomel electrodes (SCE) and silver/silver chloride electrodes are commonly used instead as they offer stable, reproducible potentials. The SCE consists of mercury coated with mercurous chloride paste and immersed in saturated potassium chloride solution, while the Ag/AgCl electrode uses silver wire coated with solid silver chloride in saturated potassium chloride solution.Energy storage devices

Hydrogen is pumped into the anode and oxygen into the cathode. The catalyst splits hydrogen molecules into protons and electrons at the anode. The protons pass through the electrolyte but electrons cannot, forcing them through an external circuit to power devices. The electrons and protons reunite with oxygen at the cathode to form water, with no waste produced.

2) Covalent bonds can form between atoms of the same element or different elements. Exceptions include cases where atoms don't achieve a full octet or share all electrons to exceed the octet limit.
3) Multiple bonds are stronger and shorter than single bonds due to greater orbital overlap in the bonding region. Bond polarity increases with difference in electronegativity between atoms.POTENTIOMETRY.pdf

A covalent bond involves the sharing of electron pairs between atoms. There are two types of covalent bonding: non-polar, with equal sharing, and polar, with unequal sharing. A non-polar bond forms between like atoms that share electrons equally, while a polar bond forms between different atoms where one atom attracts the electrons more than the other due to differing electronegativity. Examples of non-polar molecules are H2, Cl2, and O2, where the atoms share electrons equally. Examples of polar molecules are HCl and H2O, where the more electronegative atom (Cl or O) attracts the electrons slightly more, giving it a partial negative charge and leaving the other atom withWikippt
