How do I perform a titration on coca-cola or Pepsi, when I cannot see the color change because the color is too dark. The indicator is phenolphthalein.

maybe you need to do very dilute solution?

Explanation: you should have an pH meter instead of indicator.

Phosphoric acid H3PO4 have three ekvivalent points.

Another way could be using a conductivity meter.

b. acid is the correct answer @jayxboof all social media

acid : acids are those which accepts an electron-pairs.

base : bases are those which donates ab electron-pairs.

alkali : it is a base that dissolves in water. it is basically a base and the ph greater than 7.

hydroxide ion : it is a poly-atomic ion which is negatively charged.

c. 75.7

i think that is the right
