Video transcript

Hey everyone, we're told that one of the following graphs represents the titillation of a strong base with a strong acid, which titillation curve is it. So initially we had our strong base, which means that we had a high initial ph and then we titrate ID with a strong acid. So this means that in the end we will have a very low final ph and because we have a strong acid and a strong base at our equivalence point, We will have a ph of seven. Looking at our answer choices, it looks like answer choice B is going to be our answer. So we can see right here we have high initial ph and we also have an equivalent point of seven and we end up with a very low final ph. Now, I hope that made sense. And let us know if you have any questions.
