    Ok, I understand that in an acid-base neutralization, we mix an acid and a base in a solution, but I don't understand how the pH becomes neutral again after ...? Can you explain this to me please?

    Hello again :)

    Ok if I have a solution where I have to use colorimetric indicators, how do I use several at the same time to know the pH approximately? Do I simply combine them?


    thank you
