Question

Sketch the galvanic cell and determine the line notation for the following redox reaction:

Ni²⁺ (aq) + Mg (s) ⇌ Ni (s) + Mg ²⁺ (aq)

Accepted Answer

So here we again we have to sketch the galvanic cell and determine the line notation for the following redox reaction. Here we have nickel two plus ion with an oxidation number of plus two. It then goes to its natural or neutral form which gives us the oxidation number of zero. So it goes from being plus 2-0. So it's oxidation number was reduced. Therefore represents the cathode. Then we have magnesium solid in its natural state, so its oxidation number zero, it goes to being a plus two charge. So now it's oxidation number has increased. Therefore represents the anodes where oxidation has occurred. If we draw our galvanic cell here we have here our salt bridge. We have our electrode here. The solid electrode from my aunt would represent the magnesium solid. We have our wire here which connects to our other solid electrode which in this case is the nickel electrode. We have our volt meter here which reads the amount of voltage that's produced in terms of this galvanic will will take cell. The electrons are leaving my anodes going towards the cathode. Through this process we have the generation of magnesium ions. We have our negative ions traveling this way. We have some positive ions. This way Here we have the generation of Nickel two plus ions in this solution as well. Now if we're gonna talk about the line or sell notation, we first talk about our a note. So the lower oxidation state would be magnesium solid Activity here approaches community which is one. We have our phase boundary. Now we have our magnesium to ion here. We have our actual break. Then we have our Nickel two plus ion our phase boundary and that represents our line or some notation in terms of of this galvanic cell. This one is a bit more simple. We didn't have to worry about the introduction of any outside gas being formed but realize when we have gas is involved. We typically would use some type of inert solid to react and act as our electrode within the redox reaction in this one. Because both we have both the magnesium solid in the nickel solid, there is no need to introduce any type of inert solid like platinum. So this would be a simple basic question to approach when it comes to line notation and the drawing of any galvanic or voltaic cell.
