Hello, hi students, let me explain you the question.
00:03
So here, unknown metal.
00:05
Unknown metal, it is electrolyzed.
00:10
So it is electrolyzed.
00:13
So for electrolysis, it took 74 .1 second for a current of, for a current of two amperors to plate out.
00:28
To plate out, this is the current.
00:31
So to plate 0 .107 grams of metal from a solution from solution containing mno3 taken thrice.
00:45
So we have to identify the metal.
00:48
This is the question.
00:50
So coming to the solution here.
00:53
So the reduction reaction here it is the reduction reaction that is between metal metal so this is m and o3 taken price that is the solution taken plus reduction means addition of electrons it gives rise to metal yes here one mole of metal so it needs how many more of electrons it needs three moles of electrons so that is the ratio of molar ratio molar ratio between metal and electrons it is 1 is to 3 so we have to find out the moles so here this is the step 2 so in this step 2 we have to find out the moles moles of metal so how to find out the moles of metal here using current column column time column time time farad is constant farad is constant so the relationship between these it is equal to that is mold metal that is equal to column into 1 mole of electrons divided by 96 ,500 columns into 1 mole of metal divided by 3 moles of electrons...
