The sample summary paragraph which discusses an experiment and the results based on the reason why some substances require larger additions before a color change was seen is given below:

If the substance has a weak base solution (pH=8) and you add phenolphthalein, for example, you would only see a pink color change if a lot of phenolphthalein because it is used for stronger bases.

Also, when phenolphthalein is added to acids and weak bases, they tend to have a colorless coloration.

However, if phenolphthalein is added to a strong base, there would be a color change that is noticeable and it would be changed to pink.

What is a Strong Base?

This refers to the compound that has the ability to remove a proton from a very weak acid.

Hence, we can see that a summary paragraph is given above based on the use of large addition of elements to some substances before there is a noticeable color change is mentioned above.
