This chemistry explains how to solve quantitative problems associated with the electrolysis of water and the electroplating process with metals such as copper, nickel, iron, and zinc. This video explains how to calculate the mass of nickel that can be deposited onto the cathode given the electric current in amps and time in seconds. It explains how to calculate the electric current and the time as well as identifying the unknown metal and calculating the volume of Oxygen gas produced at STP in an electrolysis process. This video contains plenty of examples and practice problems.

These videos have been so incredibly helpful! I don't remember if I took chemistry in HS. Ha. that long ago. Currently, I am taking an accelerated pre-req general chemistry I and II courses online and I would be so lost without these videos. You and another tutor on KZfaq are my favs! Thank you Thank you! Keep up the great work.

Hello sir how are? Actually your lesson have really started improving my studies, however i may want to know what determies a metal to be at the anode or cathode whe drowing a galvanic cell? Thanks very much

@brianpark6299 3 жыл бұрын

💀💀💀 might be too late but it is determined by which metal is being oxidized, and the metal that is being oxidized will be the anode

@congyu3396 3 жыл бұрын

the lowest or more negative SRP value tends to be the anode while the more positive one tends more to be the cathode in a galvanic cell, if only the half-reactions are given

@hermeschi 2 жыл бұрын

Anode(+ electrode ) attracts anions ( - charge ions ). Cathode (- electrode ) attracts cations (+ charge ions). Metals are usually positive charged so they usually go to the cathode.

Hi guys, I would like to ask for help with electroplating, specifically nickel and copper plating. I need to coat some small pieces of both black steel and stainless steel. I bought nickel sulfate and copper sulfate and pure nickel (99.9%) for this purpose. As the copper anode, I used the electric wire. I dissolved nickel sulfate and copper sulfate separately in two containers in hot distilled water (I did not weigh the water to sulfate ratio), connected pure nickel (or copper wire in a second way) to the anode (+) and my steel object to the cathode (-) and set three volts on the source (I also tried some other voltage setting between 2 volts and 6 volts). My steel peace was degreased (I used both strongly degreasing alkaline bath or simply dishwashing detergent). My results in the case of nickel plating (for both black and stainless steel): steel pieces are coated by the very thin BLACK layer that can be cleaned with a sponge for dishes under running water. My results in the case of copper plating (I tried only black steel): steel pieces are coated by a rapidly increasing copper layer (I do not need to turn on the power source, just dip the steel object in the copper sulfate solution, and the cooper appears on the surface). Unfortunately, this cooper coat can be simply removed under running water only by rubbing the hand. Copper is not firmly attached to the steel. Can you help me where I do something wrong? I will be very grateful for any advice.

This explanation is not very comprehensive in my opinion, I don't think the solving process needs to be this complex

@stepanbmw Жыл бұрын

Use second Faraday's law: m=(ItM)/(zF). I is current, t is time, M is molar mass, z are the exchanged electrons, F is constant, m is the mass plated
