Buffer solutions
« on: October 11, 2018, 08:40:21 AM »

Things I don't understand

If we have a buffer, with the pH of lets say 10. However it has 5 times the amount of weak acid in it vs the weak base. How come it is better at neutralising bases than acids if the pH is so high? Why does the amount of weak acid trump the pH of the solution?

Im from NZ, our textbooks are famously dodgy and one of the statements said "The more weak acid in the buffer the better it is for neutralising acids vice versa' just by looking at it, it sounds wrong. If someone could clarify and clear the clouds that would be awesome!  :)

If there is more acid, what will be better neutralized - acid, or base?
