To make standard solutions for titration experiments, you can follow these easy steps:
Choose the Concentration: First, pick how strong you want your solution to be. This strength is called molarity (M). A common choice is a 0.1 M NaOH solution.
Find the Right Mass: Next, use this simple formula to calculate the mass you need:
Mass (g) = Molarity (mol/L) × Molar Mass (g/mol) × Volume (L)
For our 0.1 M NaOH solution (which has a molar mass of 40 g/mol) in 1 liter, it would look like this:
Mass = 0.1 mol/L × 40 g/mol × 1 L = 4 g
Mix It Up: Now, carefully weigh out the 4 grams of NaOH you calculated. Then, dissolve it in distilled water. Make sure the total volume adds up to 1 liter.
Label It: Finally, don’t forget to clearly write down the concentration and the date on the flask. This will help you keep track of the solution for later use.
