Acid-base neutralization is the process occurred here.
Explanation:
In the given question, Robert has added an indicator to vinegar.
Vinegar is dilute solution of acetic acid. And acetic acid, is an acid.
Now, in the same solution, a few drops of ammonia are added.
Ammonia when added to water, will form ammonium hydroxide, which is a basic solution.
Hence, the reaction happening here is an acid-base neutralization reaction.
