The Nature of Acid Base Titration

What is the definition of acid base titration ?

Here's the simple definition, acid base titration is titration which the titrant and analyte reacts as acid base reaction. On the early of 1800's there's limited reactant which acts asa acidic dan basic reagent. For acidic reagent is H2SO4, HCl, and HNO3. For basic reagent is K2CO3 and Na2CO3. The important thing of titration is indicator. More sensitive indicator is better than one not sensitive. The limit of reagent and indicator result in the accuracy of the result.

In the mid of 1800's NaOH firstly intoduced as base titrant. And the used of NaOH improve the result of titration. Later, discovery of phenolphthalein and methyl orange has improved the result of titration too.

Titration bases is conducted by added one solution to another solution until the equilibirium point reached. While the titration process occur, there's chemical reaction between titrant and the analyte. Titration must stop until the indicator 'says' that there's a lot of titrant on the solution on the erlenmeyer flask(usually). The indicator would change the color of solution depend on the indicator used. For example, phenolphthalein is indicator for acid base titration. In The acidic form it has colorless form, but in the basic form H+ from its structure released and has red color. Phenolphthalein is commonly indicator for titration.
