These substances are named pH indicators.
See a list on the link bellow.
It's a neutral substance, with a pH of 7.

As the name hydrochloric acid might indicate, it is an acid.
Pure water is considered to be neutral
Litmus paper is used to indicate whether a substance is acidic or basic. Blue litmus paper turns red in the presence of an acid, while red litmus paper turns blue in the presence of a base.

a weak acid
As the name hydrochloric acid might indicate, it is an acid.
A neutral substance.
a substance which is classified as neutral has a ph of 7- using universal indicator this will result in green. an acid is anything from ph1 to ph6 depending on the concentration of the acid, to neutralise an acid from a ph of 6 or below an alkali is required, so when an acid turns neutral it has either reacted with an alkaline substance or has a higher ph
Pure water is considered to be neutral
It is neither. It is a neutral substance when solvated in water.
