Preparing a 10 mol/L (Molar) sulfuric acid solution is highly concentrated and requires caution due to the corrosive nature of sulfuric acid. Here is a general procedure for preparing a 10 M sulfuric acid solution:
Ensure that you are working in a well-ventilated area or under a fume hood. Wear appropriate personal protective equipment, including gloves, goggles, and a lab coat.
Obtain a suitable container, such as a glass or high-density polyethylene (HDPE) bottle, that can safely hold and store sulfuric acid.
Carefully measure out the required amount of concentrated sulfuric acid to prepare the 10 M solution. To calculate the volume needed, you can use the formula:
Volume (L) = (moles of sulfuric acid / concentration (M))
For example, to prepare 1 L of a 10 M sulfuric acid solution, you would need:
Volume (L) = (10 mol / 10 M) = 1 L
Slowly add the measured amount of concentrated sulfuric acid to the container. It is essential to add the acid to water and not the other way around to prevent a violent reaction and splattering. Always remember the phrase "add acid to water."
While adding the sulfuric acid to the container, ensure that you stir or mix the solution gently to facilitate the dissolution of the acid. Take precautions to avoid any splashes or contact with the skin or eyes.
Once all the acid has been added and the solution is thoroughly mixed, allow it to cool if any heat was generated during the mixing process.
Label the container clearly with the concentration, date of preparation, and appropriate warning labels.
Store the sulfuric acid solution in a safe and secure location away from incompatible materials and out of reach of unauthorized individuals.
Please note that handling and working with highly concentrated sulfuric acid requires expertise and adherence to strict safety protocols. If you are not experienced in working with such hazardous substances, it is advisable to seek assistance from a trained professional or consult with a qualified chemist.
