Hello everyone, let's start the question.
00:03
In this question, we are asked to determine the volume in milliliter which is required to reach the equivalent point when we are considering 100 millilitres of 0 .016 molar h .ocl with 0 .04 molar of n -a -o -h.
00:20
So we can write that the volume volume at equivalent point at equivalence point in this case will be equal to the volume of naah volume of sodium hydroxide added to the partial volume.
00:48
Partial volume.
00:51
So now the volume of nah if we calculate it will be equal to its moles which is 0 .06 divided by its molarity which is 0 .04 which will come out to be equal to 0 .04 liters.
01:09
If you convert it into ml, it will be 40 milliliters.
01:13
So 40 milliliters is our final answer to the question.
01:20
And the total volume, this is for nahoh and the total volume will be equal to 0 .14 liters.
01:30
Let's now come to the second part of the question in which we are asked to calculate the ph after there is addition of 10 milliliters of n .a .o .h.
01:47
To the solution...
