acidic red, neutral green and alkali purple
Indicators (for example LITMUS PAPER) can detect whether a certain liquid is an acid or an alkali. Litmus Paper turns red when dipped in an acid, blue in an alkali Universal Indicators have show how strong or weak and acid or alkali is.
A pH meter uses a probe and voltmeter to measure pH digitally. Universal indicator is a mix of indicators that change colour to indicate the pH of the solution. pH meters are accurate and will detect changes quickly, whereas universal indicator is slow to change colour to indicate pH change.
Green is the color that universal indicator turns to when it is neutral.
You can use indicators (liquid or paper). Universal Indicators (UI) are the best, as with them you can tell if something is acid, neutral or alkali, depending on the colour (there will be a colour indicator). However, you can also use red and blue indicator, but they are less accurate, as although they might be acid (or alkali), they might be neutral as well, so I suggest you use UI. Hope this helps :) Source: Science lessons!
There are far too many indicators to give them all. Litmus is blue in alkali, red in acids and an in-between colour often called claret when neutral. Universal indicator is red in strong acids, blue in strong alkalis and different colours in between depending on the brand.

Not really. On the pH scale of Acids and Alkalis, Neutral is the green colour at which a liquid is neither Acid nor Alkalis.
Well, there are the three main ones which are neutral, acids, alkaliHope this helped :)

Sodium chloride is a neutral substance and will not exhibit a specific color in a universal indicator. Universal indicators change color based on the pH of a solution, not the presence of specific compounds like sodium chloride.
it is neither. pure water is neutral (PH 7)
Green is the color that universal indicator turns to when it is neutral.
alkalis / bases neutralise acids, a method in which to do this is titration where the acid is slowly added to the alkali through a burette until the mixture is neutral

A neutral solution will turn universal indicator green.
A moist litmus paper does not change its colour in neutral solutions.
