1 M Sodium Carbonate Solution: Preparation, Properties, and Uses
Introduction
Sodium carbonate, also known as washing soda, is a naturally occurring mineral that has been used for centuries as a cleaning agent, water softener, and paper manufacturing. A 1 M sodium carbonate solution is a concentrated solution of sodium carbonate (Na2CO3) dissolved in water. In this article, we will explore the preparation, properties, and uses of 1 M sodium carbonate solution.
Preparation
To prepare a 1 M sodium carbonate solution, you will need:
- Sodium carbonate (Na2CO3)
- Distilled water
Instructions:
- Weighing: Weigh out 106.0 grams of sodium carbonate (Na2CO3) and transfer it to a beaker or flask.
- Dissolving: Slowly add distilled water to the beaker or flask while stirring until the sodium carbonate is completely dissolved.
- Dilution: Continue adding distilled water until a total volume of 1 liter is reached.
