Would anyone be able to do me a huge favour?
Could you please explain the answers to:
from the following:
5b compare the pH curve with previous ones. The previous pH curves rapidly change in gradient, 5b is a very small change in gradient as the vol of base increases. This means there won't be a sharp end point. In school, you may see that only half a drop or 1 drop of titrant is needed to cause an entire colour change when you approach the endpoint. This will not happen with whatever 5b is because it is gradual.
