In this question, it says that what volume of a 0 .195 molar concentration of potassium hydroxide solution is required to neutralize 23 .5 milliliter of a 0 .306 molar concentration of our hydrobromic acid solution.
00:18
So let's solve it.
00:20
So we have our first part of the question, our c1, that is the concentration of our potassium hydroxide solution is given as 0 .195 molar.
00:36
Our v1 of potassium hydroxide solution is unknown.
00:43
Our concentration of our hydrobromic acid is given as 0 .306 molar.
00:51
Our volume of our hydrobromic acid is given as 23 .5 milliliters.
01:00
So what we find for our v1 or the volume of our potassium hydroxide solution which is equal to c2 v2 divided by c1.
01:11
So our v1 will be equal to our c2 which is 0 .306 times our v2 which is 23 .5 divided by our c1 which is 0 .195.
01:29
So we have our v1 being equal to 36 .88 milliliters.
01:41
Thank you.

In the second part of the question, it says that what volume of a 0 .398 molar concentration of percloric acid solution is equal to neutralize 13 .3 milliliter of a 0 .160 molar concentration of sodium hydroxide solution.
02:03
So i will give you the concentration, c1 of our percloric acid which is equal to 0 .393 molar.
02:20
We need to find for the volume of our percloric acid which is unknown...
