a battery, the cathode polarity is positive. In general, in a device the cathode is the terminal from which the current flows out, whereas the anode is the terminal from which the current flows in from outside. In chemistry, the cathode is considered as the electrode at which the electroch...
The scientific study of matter's characteristics and behaviour is known as chemistry.andare different from the normal vocabulary. It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up compounds and their composition, s...

What is a redox titration in chemistry? How do you determine if a redox reaction is spontaneous? Are acid base reactions redox? How do you balance a redox reaction using the ion-electron method? What reaction (oxidation or reduction) occurs at the cathode of a voltaic cell?
The object to be plated is connected as the cathode in the electrolyte solution and then passing electric current is passed through the anode which causes the ions to be deposited to the material. Methanesulfonic acid is used as the acid electrolyte in the electroplating because many metals which...

As a general rule of thumb, good reducing agents are poor oxidizing agents, and good oxidizing agents are poor reducing agents. Another way to estimate the relative strength of an oxidant is to determine its standard electrode potential, measured in volts. High potentials in the cathode half ...
