Question
A technique used to determine the concentration of a solution by reacting it with a solution of known concentration
Solution
The technique you're referring to is called titration. Here are the steps involved in this process:
-
Preparation: First, you need to prepare the solution with a known concentration, also known as the titrant. This is usually placed in a burette, a long, graduated tube with a tap at the bottom.
-
Sample Measurement: Next, you measure a specific volume of the solution whose concentration you want to determine. This is known as the analyte, and it's usually placed in a flask or beaker.
-
Indicator Addition: You then add a few drops of a chemical known as an indicator into the analyte. The indicator changes color when the reaction between the titrant and the analyte is complete.
-
Titrant Addition: You slowly add the titrant into the analyte while stirring the solution. You continue this until the indicator changes color, signaling that the reaction is complete.
-
Calculation: Finally, you calculate the concentration of the analyte. This is done using the volume of the titrant that reacted with the analyte and the known concentration of the titrant.
This is a basic overview of the titration process. The exact steps can vary depending on the specific type of titration being performed.
