Good, now we have the volume it's given.
00:03
The volume is around 170 ml.
00:07
Concentration of the pyramidine solution is also 0 .7322 m.
00:13
Concentration of hcl, this is pyramidine hcl is 0 .2393 m.
00:21
And p is also provided.
00:25
We are having 8 .77.
00:29
That's good.
00:29
Now first thing to do is calculate the moles of the primidine and hcl.
00:36
So moles of primidine will be the concentration 0 .7322 multiplied by 170 over 1000 to get 0 .12505 moles.
00:51
And that moles of moles hcl will be also 0 .2393 x 170 over 1000 to give us 0 .040681 moles.
01:12
Okay so that's quite so the next thing is that equivalent point remember all of the permadine will react with the hcl to form pyrimidinium chloride okay so we're looking at c5h5nh this is i only expect and i expect this pyridine to be fully consumed so so the mislet kb expression would be ohc5h5nhc5h5n...
