An acid-base titration is a quantitative analysis technique used to determine the concentration of an acid/base by neutralizing it with a standard solution of acid/base of known concentration.
In this kind of titration, a drop of an indicator that changes color to indicate the endpoint is added to the beginning. The indicator changes color as the pH of the solution changes. To determine the equivalence point and minimize indicator error, have to use an appropriate indicator.
Which titration fall under the category of acid base titration?
The estimation of weak and strong acids in titration falls under the category of acid-base titration.
According to the nature of acid and base neutralization reactions, they are classified as:
- Strong acid and strong base:
Example-HCL + NaOH → NaCl + H2O
- Strong acid and weak base:
Example-HCl + NH4OH → NH4Cl + H2o
- Weak acid and strong base:
Example- CH3COOH + NaOH → CH3COONa + H2O
- Weak acid and weak base:
Example- CH3COOH + NH4OH → CH3COONH4 +H2O
In chemistry, the concentration or measurement of an analyte in a sample can be determined using titration. There are mainly four titration classifications based on the interaction of the sample with the added titrant. In an acid-base titration, the acid or base concentration can be determined. Therefore, the result will indicate how strong or weak the acid or base is.
