1760 - What is the principle of acid-base titration and quantitative analysis?
Imagine you have a glass of lemon juice with some unknown amount of acidity, and you want to know exactly how much of it is acid.
Acid-base titration is a scientific method to figure this out. Here's how it works:
- We use a special liquid called a 'base' that can neutralize the acid.
- We slowly add this base to the lemon juice while measuring how much base we're adding.
- When all the acid in the lemon juice is neutralized by the base, we stop adding the base. This point is called the 'endpoint.'
- By knowing how much base we added to reach the endpoint, we can calculate the exact amount of acid that was originally in the lemon juice.
This method is used for quantitative analysis, which means we're trying to measure the exact amount of something (in this case, the acid) in a substance.
