Hello students, in this video we are going to check the reactivity of metals, certain metals with hcl.
00:11
The metals that we are going to check it with are magnesium, zinc, iron, copper, aluminium.
00:23
So, we will check it against h which is the electropositive part of the hcl.
00:28
We know that metals react by losing electrons.
00:36
That means they are good reducing agent, that means that they are getting oxidized in the process.
00:42
So, if their oxidation potential is more than they are more reactive.
00:58
So, basically if their oxidation potential is than that of hydrogen, they are more reactive.
01:05
So, the oxidation potential of hydrogen when it is getting oxidized from h2 to 2h plus is 00 volts.
01:17
So, let us write the oxidation potential of all these metals.
01:23
The oxidation potential of magnesium when it is converting from mg to mg2 plus is 2 .36 volts.
01:36
For zinc it is 0 .76 volts...
