What is difference between hydrogen sulfide and hydrogen sulphide?
There is no difference between hydrogen sulfide and hydrogen sulphide. The term "sulfide" and "sulphide" both refer to the chemical compound H2S, also known as hydrogen sulfide. The difference in spelling is simply a matter of regional or historical variation.
What kind of bond is Hydrogen Peroxide?
covalent the electronegitivity of carbon is 2.1 the electronegitivity of oxygen is 3.5 if the difference between them is less then 1.67, then the bond is covalent. if the difference between them is more than 1.67, then the bind is ionic 3.5-2.1=1.4 so the bond of hydrogen peroxide is covalent because the difference between the electronegitivities is less than 1.67
Why hydrogen bonding is not present in hydrogen sulphide?
Hydrogen bonding occurs between hydrogen atoms and a highly electronegative atom like oxygen, nitrogen, or fluorine. In hydrogen sulfide (H2S), sulfur is less electronegative than oxygen, so the hydrogen bonding is weaker and not significant enough to cause hydrogen bonding in H2S.
What is the attraction between hydrogen and oxygen atoms in a water compound called?
The attraction between hydrogen and oxygen atoms in a water compound is called a hydrogen bond. Hydrogen bonds form due to the difference in electronegativity between the hydrogen and oxygen atoms, creating a partial positive charge on the hydrogen atom and a partial negative charge on the oxygen atom.
What is the difference between dihydrogen and hydrogen?
Dihydrogen is a term sometimes used to refer to molecular hydrogen (H2), which is a diatomic molecule composed of two hydrogen atoms. Hydrogen typically refers to atomic hydrogen (H), which is a single hydrogen atom. The main difference is in the number of atoms in the molecule.
How should the values found using the zinc electrode as a standard compare with those based on the standard hydrogen electrode?
Perhaps a rephrasing of the question would help; I've never seen a hydrogen electrode so I don't know how it compares to zinc. The process being done would probably also help (are you electroplating or separating oxygen from hydrogen or ...?), as would the solution the electrodes are immersed in (does the solution react with zinc at room temperature, is it being used in a gas, ...?)
How does a pH electrode work to measure the acidity or alkalinity of a solution?
A pH electrode works by measuring the electrical potential difference between a reference electrode and a glass electrode. The glass electrode is sensitive to hydrogen ions in the solution, which determines the acidity or alkalinity. The pH value is calculated based on this potential difference.
Why is platinum coated with platinum black used in the standard hydrogen electrode?
The platinum black provides a very high surface area that promotes the speed of reaction at the electrode and thereby virtually eliminates overpotential at the standard hydrogen electrode. An overpotential would lead to misleading values of potential of other electrodes compared with a standard hydrogen electrode that manifested overpotential.
How does a pH electrode work?
A pH electrode works by measuring the electrical potential difference between a reference electrode and a glass electrode. The glass electrode contains a special membrane that responds to changes in hydrogen ion concentration, which is used to determine the pH of a solution.
How do pH electrodes work to measure the acidity or alkalinity of a solution?
pH electrodes work by measuring the electrical potential difference between a reference electrode and a glass electrode in contact with the solution. The glass electrode responds to the hydrogen ion concentration in the solution, which is directly related to its acidity or alkalinity. The pH value is then calculated based on this potential difference, providing a measure of the solution's acidity or alkalinity.
What are the parts pH meter?
A pH meter typically consists of a probe with a glass electrode, a reference electrode, and a meter that displays the pH value. The glass electrode measures the hydrogen ion concentration in a solution, while the reference electrode provides a stable reference point. The meter then calculates and displays the pH value based on the difference in electrical potential between the two electrodes.
What can increase the voltage difference between a metal electrode and a solution?
If electrons are left behind in metal this will increase the voltage difference between a metal electrode and a solution. Also if the solution becomes more positive this will cause an increase.
What is the difference between standard theory and extended standard theory?
What is the difference between standard theory and extended standard theory?
What is difference between standard and non standard?
the difference is that standard is being used by majority
Describe the construction of calomel electrode?
It consists of tube in the bottom of which is a layer of mercury ,over which is placed a paste of Hg+HgCl2.The remaining portion of cell is filled with a solution of normal or decinormal or saturated solution of KCl. a platinum wire dipping into the mercury layer is used for making electrical contact. the side tube is used for electrode is formulated as;Hg,Hg2Cl2,KCl. the electrode can be coupled with the hydrogen electrode of unknown pH.
The difference between actual and standard cost caused by the difference between the actual quantity and the standard quantity is called the?
The difference between actual quantity and standard quantity is called the material quantity variance.
What is the relationship between voltage and electrode in an electrical circuit?
In an electrical circuit, the voltage is the force that pushes electric current through the circuit. The electrode is the conductor that allows the current to flow. The relationship between voltage and electrode is that the voltage creates a potential difference between the electrodes, which drives the flow of electrons through the circuit.
