Hi, now we will discuss about what mass of calcium is deposited by the electrolysis of calcium bromide by using the current by 30 ampere in 10 hours time.
00:13
That we have to find out.
00:14
Before that, first we will find the what is the charge supplied by 30 ampers in 10 hours.
00:22
So this can be charge supplied can be found by using the equation.
00:27
Charge q is equal to i into t i t by substituting the values current is 30 amperors time is given in hours it should be in seconds so it should be multiplied with 60 into 60 10 hours for the conversion to minutes multiplied with 60 then the value should be converted into seconds by multiplying with 60 so 6 is many seconds by multiplying this we'll get 108000 ampere second.
01:11
Amper second can also be written as fulm.
01:15
The unit coolum.
01:17
The charge can be expressed in coulum c.
01:21
We know that 96 ,500 fulum charge carry one mole of electrons.
01:29
1 faraday, 96 ,500.
01:31
1 faraday or 96 ,500 fulm charge is carried by 1 mole of electrons.
01:45
Here the charge supplied in the equation is 108000000 fulums charge it will be carried by how many moles of electrons we have to find out so this can be solved by simple unitary method 1080000 columns into 1 by 96 ,500 columns...
