When combined two gases have a pressure of 4.0 atm. If one has a pressure of 1.5 atm, the pressure of the second gas will be; 4.0 atm- 1.5 atm = 2.5 atm.
Total pressure = Partial pressure of one gas + partial pressure of the second gas.Therefore; the pressure of the second gas will be; 2.5 atm
Answer:
oxidation takes place at the anode while reduction takes place at the cathode.
Explanation:
In the process of electrolysis the electric current is passed accross an ionic compound, the compound could either be in it's molten state or dissolved in a solvent. When there is connection between the anode and cathode are by a wire, there is always a flow of electrons from anode to cathode.
A redox reaction reffers to a chemical reaction in which there are both process of oxidation and the process of reduction i.e loss of election and gain of electrons occured simultaneously.
During the process of electrolysis, there is oxidation of an ion at anode which is the negative charged electrode, reduction as well takes occur at cathode which is the positively charged electrode at the same time.
