Will Magnesium spontaneously reduce Copper ion (Cu+2) to Copper (Cu)? Explain. What is the Edegree?

Mg(s) + Cu+2(aq)---> Cu(s) + Mg+2(aq)

Expert Solution

In Electro chemistry , involves an oxidation-reduction process . Here oxidation means loss of electrons by substance, reduction means gain of electrons by substance .

The substance that is reduced is oxidising agent , the substance that is oxidised is redusing agent .

In general , metal tend to make good reducing agents, because they can only be oxidise. The redusing ability is given by the activity series . " The more active metal is able to reduce the less active metal ion ".

Magnesium metal is able to reduce cooper(II) ions in solution to form Magnesium ions & Copper metal .

Mg(s) + Cu⁺² --------->Mg⁺² (aq)+Cu(s)

A magnesium ion (Mg+) moves in the xy-plane with a speed of 2.80 ✕ 103 m/s. If a constant magnetic field is directed along the z-axis with a magnitude of 2.75 ✕ 10−5 T, find the magnitude of the magnetic force acting on the ion and the magnitude of the ion's acceleration. (a) the magnitude (in N) of the magnetic force acting on the ion _______ N (b) the magnitude (in m/s2) of the ion's acceleration _______ m/s2
