Silver Nitrate Standard Solutions - How to make them, and SAVE MONEY!
How to Make your own Silver Nitrate Standard Solutions
You can save a lot of money by making your own Silver Nitrate Standard Solutions! It's Easy!
What you need
1 - A Volumetric Flask. ( from a chem store, catalog, or eBay )
2 - An Accurate Scale. ( there are very good ones on eBay )
3 - De-Ionized -or- Distilled Water. ( don't use tap water! )
4 - High Purity Silver Nitrate. ( you can buy it on this website )
1 - Find the concentration of the solution you want to make, from the table, above.
2 - Carefully weigh the exact amount of High Purity Silver Nitrate you need.
3 - Add the Silver Nitrate powder to the empty Volumetric flask.
4 - Add about half of the water, swirl the flask to dissolve all of the Silver Nitrate.
5 - Carefully add the rest of the water, until the water Meniscus reaches the mark on the flask.
6 - That's it. You can pour your solution into another bottle at this point.
Important: Use High Purity Silver Nitrate only. ( we sell High Purity Silver Nitrate )
Important: Use De-Ionized -or- Distilled Water only. ( never use tap water )
Important: Store your solution capped. Don't let it evaporate - that will concentrate it!
HINT: Store your standard solutions in Glass Containers. (not soft plastic)
HINT: Silver Nitrate solutions can be stored in type PETE 1 (polyethylene terephthalate ester) Plastic.
HINT: The solutions are not light sensitive. You don't need dark bottles.
HINT: After pouring your solution from the Volumetric flask, add a pinch of salt to the flask, then rinse and drain at least 3 times.
HINT: Rinse your Volumetric Flask with Distilled Water, then let it dry, before storing it.
HINT: If you don't use High Purity Silver Nitrate, your solution won't be colorless, like it should be.
HINT: With Silver Nitrate Standard Solutions, Normal and Molar have the same meaning. (because it's Valence is +1)
HINT: 100 gram Capacity Digital Scales, accurate to 0.01 grams, can be found on eBay for under $20!
KNOW THIS: One Mole of Silver Nitrate weighs 169.87 grams. So a 1.0N solution is: 169.87 grams diluted to a volume of 1 Liter.
KNOW THIS: One Mole of Silver Nitrate weighs 169.87 grams. So a 0.1N solution is: 16.987 grams diluted to a volume of 1 Liter.
