So the answer for this is yes, you can. And the reason is for a tight creation. As long as the moles off acid is equal to the number of malls off the base, you can have a complete reaction. And so, um, I see a lot of people saying that more weak base has to be added because we'd best doesn't associate completely. But what they forget is that they're thinking off it in this way. For example, you have ammonia, which is in water, and you get ammonia. I'm and always whiteness. And obviously this is a reversible reaction and it doesn't go to completion, doesn't go to completion. But when you are adding a strong acid, the strong acid like HCL immediately dissociate to form a presidency or minus science. On my virtue off the p k. The virtue of the K they will react with. So the young one ammonium part will react with the two right to give you ammonium chloride. And the H designs will react with Deutsche minor science to give you water, which means it will push this reaction in this direction because this will be used up and it has to be, um, replenished, so the reaction will move in this direction automatically for using a strong acid will actually enhance your reaction, and it won't just stay in this dissociated forms so you can neutralize a strong acid with the weak base, using equal minorities and equal wagons.
