A weak acid is a acid with a pH scale just below 7. The closer to seven the weaker an acid it is, a acid with a lower number is a stronger acid then an acid with a higher number. (no acids have a pH above 7)

The green only comes into play if the liquid you are testing is neutral.

What color does ascorbic acid and universal indicator make?
Green
What is the advantage of knowing the pKa of an acid-base indicator?
The advantage of knowing the pKa of an acid-base indicator is that it tells you the approximate pH value at which the color of the indicator changes. For example, if the pKa of an indicator is 5, then it means that it's going to change colors at around pH 5.
What color does an acid turn the indicators?
If a substance is an acid, it would turn red on a pH indicator
Does an acid or a base react with a predictable indicator to produce a color change?
both acid and base
What will an indicator do in the presence of an acid or base?
This indicator changes his color.
