Who identified electrons to have a negative charge?
J.J. Thomson is credited with identifying electrons to have a negative charge through his experiments with cathode rays in the late 19th century.
Where does reduction occur in an electrochemical cell?
The cathode.
What following piece of equipment was used by jj Thomson to find electrons?
J.J. Thomson used a cathode ray tube to discover electrons. By passing an electric current through the tube, he observed the deflection of a beam of electrons, which led to his conclusion about the existence of electrons.
Which element is produced at the negative electrode (cathode)?
The element forming at the cathode will depend on what elements are present. Reduction takes place at the cathode, so whatever element is being reduced, that is the one that will be produced at the cathode.
Is cathode rays are material particles?
Cathode rays are streams of electrons that travel from the negatively charged cathode to the positively charged anode in a cathode ray tube. They are not material particles in the traditional sense because they do not have mass or volume, but rather behave as electron beams.

WHO INVENTED THE CATHODE RAY TUBE?
Why sulpuric acid is used in battery?
In a battery, there is a cathode, that gives off electrons in a chemical reaction, and an annode, which absorbs electrons in a complimentary chemical reaction. A car battery uses lead (which I will call by its chemical symbol Pb) as the cathode, and lead oxide (PbO) as the annode, both of which are bathed in Sulphuric acid. Lead is oxidized by water in the reaction Pb + H2O = PbO + 2H+ + 2e- (the symbol H+ stands for a hydrogen ion, and e- stands for electrons). The reaction at the annode is PbO + 2H+ + 2e- = Pb + H2O This regenerates the lead, making the car battery rechargable. The Sulphuric acid is a source of H+ which is used to get the reaction going at the annode (the cathode reaction is also a source of H+, but the reaction at the annode requires a large amount of H+ to get going) so Sulphuric acid can be considered a catalyst for this reaction.
What is the long leg on an LED called?

What is the long leg on the led called?

How does a hollow cathode lamp work and what is its role in analytical chemistry?
A hollow cathode lamp works by passing an electric current through a gas-filled tube with a cathode at its center. The cathode emits light at specific wavelengths when the current is applied. In analytical chemistry, the lamp is used as a light source in instruments like atomic absorption spectrometers to analyze the concentration of elements in a sample based on the light absorption characteristics of the elements.
How does a hollow-cathode lamp function in analytical chemistry techniques?
A hollow-cathode lamp in analytical chemistry techniques functions by using a cathode made of a hollow tube filled with a specific metal. When a voltage is applied, the metal atoms in the tube are excited and emit light at specific wavelengths. This emitted light is then used for elemental analysis in techniques such as atomic absorption spectroscopy.
What is the function of a hollow cathode lamp in analytical chemistry techniques?
A hollow cathode lamp is used in analytical chemistry techniques to produce specific wavelengths of light for atomic absorption spectroscopy. This lamp helps to excite atoms in a sample, allowing for accurate measurement of their concentration in the sample.
What is the function of hollow cathode lamps in analytical chemistry techniques?
Hollow cathode lamps are used in analytical chemistry techniques to produce specific wavelengths of light for atomic absorption spectroscopy. This light helps identify and quantify elements in a sample by measuring the absorption of light at characteristic wavelengths.
Can you use cpvc pipes for underground gas piping?
Only if it is wraped pipe -- And prime and wrap fittings also and install a annode making sure your annode is lower than your pipe
What causes a bad odor to develop inside your water heater?
Most water heaters have what is called a "sacrafical annode." This is fitted to save the heater from "agressive" water, hence the use of the word sacrafical. The Annode is sacraficed to save the heating vessel. If there is even a tiny amount of hydrogen sulphide (H2s) present in the water, the annode rod will make the problem worse and heated water will smell like rotten eggs. Try removing the annode rod and I bet it will be the end of your problem. Please note that removing the rod may affect your warrenty. I would love to know if this helps, I am pretty sure it will.

What did William Crookes study?
William Crookes was a British scientist who studied spectroscopy and cathode rays. He made significant contributions to the fields of chemistry and physics, and is best known for his discovery of thallium and for his work on vacuum tubes.
