So the reaction plus sodium hydroxide is going to be the sodium a .p.
00:25
Plus water.
00:28
So we've been given 25 millimeters of 0 .1 .00 molar sodium hydroxide solution.
00:51
So another molarity is given by the number of the number.
00:57
Of moles or the volume in liters or can also say the number of moles over volume in millilitres times a thousand so i'm going to be using this one similarity which is 0 .1 is going to be called to the number of moles times a thousand for the volume in the solution which is 25 millimeters, right? so if you do the math, the number of moles, that's going to be of sodium hydroxide, that's going to be equal to just the second, that's going to be 0 .0025.
02:15
So i just do some cross multiplication here, right? so let me just do that here.
02:21
So n is just 25 times 0 .1 over 1 ,000.
02:29
It's going to give you that.
02:33
All right.
02:35
So now, as one mole of sodium hydroxide react with one mole of khp, and we are using the more ratios here, right? so you can see that it's balanced...
