Chemistry | Acids and Bases | 8-mark questions (Back titration)

How to answer those long 8 marks questions on Acids and Bases? Well, here's a quick lesson on how to approach them...
This is called back titration. For those of you in Matric (Grade 12) or University, this lesson will be really helpful.
Enjoy

    So if i react NaOH with something and some NaOH remains after that. Does the concentration remain the same? And if yes, why does it remain the same?

    I always make an example with Oros (my favourite summer drink, yummy!!!). Suppose you make a mixture into a jug... Does the taste change as you use it? No... The taste is concentration.
