A buffer with ph value is equals to 9 .85 right this is given to us for ch3nh2 and ch3nh3cl right in water.
00:25
So this is for sure that there should be a comparison between these two only these two quantities right.
00:33
So what can you conclude about the relative concentrations of ch3nh2 and ch3nh3cl in this buffer right.
00:45
So for ch3nh2 right one more thing is given to us which is pkb, pkb would be equals to 3 .36.
00:59
All right so now what you could find out what could you relate with it pkw relation between relation between pkw and pkb is equals to that would be pkw is equals to pka plus pkb this is so simple as that right for any buffer you can find out right.
01:33
So it would be pka value would be equals to why we are finding so that we can compare the value of ph and pka right so that we can find out.
01:47
So i will tell you three cases as well that how can you compare it right and how can you get into the answers right.
01:55
So now here it would be pkw is what that is a constant value that is 14 itself minus 3 .36 right.
02:05
So how is that it should be 3 .14 minus 3 .36 that would be 10 .64, 10 .64 right this is pk value.
02:21
Now what you could say right so there is a comparison ph and pka...
