Heya!! Here is your answer!

$<b><Font size=4>Indicators$

$<b>Indicators, or well-known as acid-base indicators are used to find wether a substance is acidic or basic.$

There are mainly three types of indicators:

✨Natural indicator

✨ Synthetic indicator

✨ Olfactory indicator

There are different kinds of indicators like litmus paper, Phenolpthalien, Turmeric juice,China-rose juice and red-cabbage juice.Noare w,I'll classify each to you.

⭐Litmus paper is a natural indicator.It is obtained from a kind of plant known as Litchens.There are two types of litmus paper.✨Red litmus & ✨Blue litmus.

✨Red litmus turns blue when it is dipped in a solution of base.

✨Blue litmus turns red when it is dipped in a solution of acid.

⭐Plenolphthalein in alcohol is another indicator.It is colourless. It remains colourless when dipped in acid and turns red or pink when dipped in basic medium.

⭐Turmeric juice is another.It turns reddish to deep brown in acidic medium and remains yellow I'm acidic or neutral medium.

⭐ China-rose juice is another example of a natural indicator.It turns green in basic and red in acidic solution.

⭐ Red-cabbage juice is another indicator which is purple in colour.It turns green in basic medium and red in acidic solution.

Now,finally let me tell you what is an acid and a base.

⭐An acid is a substance which dissolves in water to give H+ ions.

⭐A base is a substance which reacts with acids to form a neutralisation reaction.

✨ Hope it helps you ✨
