How Can You Use Titration to Determine the Concentration of an Acid or Base?

Titration is a really cool method you can use to find out how strong an acid or a base is.

Once you get the hang of it, it's pretty simple! Here’s how it usually works:

Set Up Your Tools: First, you’ll need a burette. This is a special tube that holds a liquid. Fill it with a standard solution, which is a liquid with a known strength, usually a base if you are testing an acid.
Get Your Sample Ready: Next, take the acid solution you want to test and put it in a flask. It’s a good idea to add a few drops of an indicator. This is a substance, like phenolphthalein, that will change color when you reach the endpoint of the test.
Start Titrating: Now, slowly add the base from the burette into the acid solution in the flask. Make sure to swirl the flask gently. Keep an eye out for a color change, which means you are almost done.
Do Some Math: When you see the color change, that means you've reached the endpoint. Write down how much base you used. Then, you can use this formula to find out the concentration of the acid:

$C_1V_1 = C_2V_2$

Here, $C_1$ is the strength of the acid, $V_1$ is the volume of the acid, $C_2$ is the strength of the base, and $V_2$ is the volume of the base you used.

Titration is a fun way to learn about how acids and bases react with each other. Plus, it’s a great way to practice hands-on skills!
