A

pH of sample flask

21
Q

What is x-axis of pH curve graph

A

volume of titrant added to sample

22
Q

What is endpoint

A

y coordinate that indicated pH=7
There is a colour change

What is equivalence point

A

x coordinate that shows what volume of titrant needed to reach desired endpoint
perfect amount for neutralization

24
Q

What do sections of pH curve mean?

A

they show how as ions of base or acid are added, the ph starts to sharply curve until it plateaus
