What are different types of acid-base indicators?
Examples of acid-base indicators include red cabbage juice, litmus paper, phenolphthalein and. An acid-base indicator is a weak acid or weak base which dissociates in water to produce the weak acid and its conjugate base, or the weak base and its conjugate acid. The species and their conjugate are of different colours.

Which of these is the main goal of any titration?
The purpose of titration is to determine an unknown concentration in a sample using an analytical method.
What is the function of an indicator in titration?
The common application of indicators is the detection of end points of titrations. The colour of an indicator alters when the acidity or the oxidizing strength of the solution, or the concentration of a certain chemical species, reaches a critical range of values.
How many types of acid-base indicators are there?
Because acidity and alkalinity relate to pH, they may also be known as pH indicators. Examples of acid-base indicators include litmus paper, phenolphthalein, and red cabbage juice. There are basically 6 types of acid base indicators.
