1M Sodium Carbonate Preparation
Introduction
Sodium carbonate, also known as washing soda, is a common laboratory reagent used in various applications such as pH buffering, precipitation reactions, and as a cleaning agent. A 1M solution of sodium carbonate is a commonly used concentration in many laboratory procedures. In this article, we will outline the preparation of a 1M sodium carbonate solution.
Materials
- Sodium carbonate (Na2CO3)
- Distilled water
Preparation
To prepare a 1M sodium carbonate solution, you will need to dissolve 106.0 grams of sodium carbonate in 1 liter of distilled water.
Step 1: Weighing
Weigh out 106.0 grams of sodium carbonate using a balance or scale.
Step 2: Dissolving
Transfer the weighed sodium carbonate to a 1-liter beaker or flask. Gradually add distilled water to the beaker while stirring until the sodium carbonate is fully dissolved.
Step 3: Mixing
Stir the solution thoroughly to ensure that all the sodium carbonate has dissolved.
Step 4: Filtration (Optional)
If desired, filter the solution through a filter paper or membrane to remove any undissolved particles.
Calculations
The molar mass of sodium carbonate (Na2CO3) is 106.0 g/mol. To prepare a 1M solution, you need to dissolve 106.0 grams of sodium carbonate in 1 liter of distilled water.
Molarity Calculation
Molarity (M) = moles of solute / liters of solution = 1 mole / 1 liter = 1M
Tips and Precautions
- Always handle sodium carbonate with care as it can cause skin and eye irritation.
- Wear protective gloves and eyewear when handling the substance.
- Ensure that the distilled water is free of contaminants and impurities.
- Store the prepared solution in a clean, labeled container.
Conclusion
In conclusion, preparing a 1M sodium carbonate solution is a straightforward process that requires careful measurement and dissolution of sodium carbonate in distilled water. By following the steps outlined above, you can successfully prepare a 1M sodium carbonate solution for your laboratory needs.
