Answer:

Limitations of litmus paper and phenolphthalein:

They do not give the numerical pH value.

Can differentiate only between a very strong acid and base.

The colour change can be for reasons other than acid- base reactions.

Explanation:

The litmus test is quick and simple, but it suffers from a few limitations. First, it's not an accurate indicator of pH; it does not yield a numerical pH value. Instead, it roughly indicates whether a sample is an acid or a base. Second, the paper can change colors for other reasons besides an acid-base reaction.
