Question

what are acids and natural indicators
​

Answer 1

Answer:

An acid is any hydrogen-containing substance that is capable of donating a proton (hydrogen ion) to another substance. A base is a molecule or ion able to accept a hydrogen ion from an acid. Acidic substances are usually identified by their sour taste

Indicators are chemical compounds that tell us whether a substance is acidic or basic by changing its colour. When added to an acidic solution or a basic solution, indicators change their colour and this change in colour is different for the acids and bases. The indicator thus help us to decide whether a given solution is acidic or basic in nature.

The indicators that are obtained from plants are known as natural indicators.

Answer 2

❥︎An acid is a molecule or ion capable of donating a proton (hydrogen ion H+) (a Brønsted–Lowry acid), or, alternatively, capable of forming a covalent bond with an electron pair (a Lewis acid). The first category of acids are the proton donors, or Brønsted–Lowry acids.

❥︎Indicators are chemical compounds that tell us whether a substance is acidic or basic by changing its colour. ... The indicators that are obtained from plants are known as natural indicators. Examples – Turmeric, china rosa, red cabbage and grape juice.
