If you want the general term, it's "indicator".
If you want a specific one ... methyl red, litmus, or bromothymol blue are some examples (there are lots of others).

What substance like litmus will change colour in acids and alkalis?
Sorry but I don't know
How don you test for acids and alkis?
You can test for acids and alkalis by two different ways: -Litmus paper reactions -Universal indicator reactions Both ways will allow you to see colour changes and this will tell you if it is an acid or an alkali and what PH it is.
Why acids are useful?
Otherwise we would have nothing to neutralise alkalis with, the whole would be alkalis rather than acids and alkalis.
Are acids plus alkalis friends or foes?
The reaction between acids and alkalis is a neutralization reactin.
Are alkalis and acids dangerous?
Acids and alkalis with a high pH (1 or 2 for acids and 14 or 15 for alkalis) can be dangerous, like hydrochloric acid which can cause damage to the skin if contact with the acid is made. Acids and alkalis with a low pH (5 for acids and 11 for alkalis) aren't dangerous, as vinegar is an acid with that pH and toothpaste is an alkali.
Is there more than one indicator that changes colour in acids or alkalis?
No, many types of color indicators are known.
Chemical that changes colour in acids and bases?
It's an indicator.
What is the name of the chemical that changes colour in acids and bases?
phenolphthalein

Does Neutral mean safe?
Not really. On the pH scale of Acids and Alkalis, Neutral is the green colour at which a liquid is neither Acid nor Alkalis.
What chemical is opposite of an acid?
Bases and Alkalis are the opposites of acids. Alkalis are bases dissolved in water. When combined in the equal quantities, they neutralise each other.
Do acids counteract alkalis?
Yes, acids neutralize alkalis and inverse.

Household acids and alkalis?
households acids and alkalis is formic acid and syitric acid
Are acids plus alkalis friends or foes?
The reaction between acids and alkalis is a neutralization reactin.
What is the purpose of an indicator in science?
An indicator usually means a substance which changes colour depending on what other substances are present. The most common type are acid/alkali indicators such as litmus, which is red in acids and blue in alkalis.
