How to prepare 14M Sulfuric acid
How much? It makes a difference if you want 1 mL or 1000 mL.
mols you need = M x L
Substitute M and L and solve for mols.
Then mols = grams/molar mass. You know mola rmass and mols, solve for grams.
Add some water to the size flask you have chosen, add the grams H2SO4 SLOWLY AND WITH SWIRLING, add DI water to the mark on the flask and mix thoroughly. Stopper.
Technically, you can't do this because H2SO4 doesn't come packaged like that but I suppose this is a working problem and not a practical problem.
Preparing 14M sulfuric acid involves using a concentrated solution of sulfuric acid and diluting it to the desired concentration. Here's how you can do it:
1. Safety first: Sulfuric acid is highly corrosive and can cause severe burns. Ensure you have adequate personal protective equipment, such as gloves, goggles, and a lab coat, before handling it.
2. Calculate the required amounts: To prepare 14M sulfuric acid, you need to know the concentration of the starting solution. Let's assume you have a concentrated sulfuric acid solution at 98% purity. The molarity of the starting solution can be calculated using the formula:
M1V1 = M2V2, where M1 is the concentration of the starting solution, V1 is the volume of the starting solution you will be using, M2 is the desired concentration (14M), and V2 is the final volume of the diluted solution.
3. Measure the starting solution: Using a pipette or a measuring cylinder, measure out the required volume of the concentrated sulfuric acid solution. Ensure you handle the concentrated acid with extreme caution and follow proper safety protocols.
4. Dilute with water: Transfer the measured volume of the concentrated sulfuric acid solution into a suitable container, such as a glass beaker or a volumetric flask. Then, carefully add the appropriate amount of distilled water to achieve the desired final volume. For example, if you want to prepare 500 mL of 14M sulfuric acid, you would add enough water to bring the total volume up to 500 mL.
5. Mix thoroughly: Gently swirl the solution or use a glass rod to mix the contents until they are thoroughly mixed. Avoid splashing or creating aerosols, as sulfuric acid fumes can be hazardous.
6. Label and store: After preparing the 14M sulfuric acid solution, be sure to label the container with the concentration, date, and any relevant safety information. It is best to store the solution securely in a properly labeled container in a well-ventilated storage area, away from flammable materials and incompatible chemicals.
Remember, working with concentrated sulfuric acid can be dangerous, so always exercise caution and follow appropriate safety guidelines when handling and preparing chemicals.
