How to prepare 0.02N silver nitrate solution
To prepare a 0.02 N (Normal) tableware nitrate (AgNO3) result, you'll need to follow these way:
Step 1: Determine the molar mass of tableware nitrate (AgNO3).
So, firstly we calculate the molar mass of Ag, N and O.
Here,
a) Ag (tableware) has a molar mass of 107.87 g/mol.
b) N (nitrogen) has a molar mass of14.01 g/mol.
c) O (oxygen) has a molar mass of16.00 g/mol.
Total molar mass of AgNO3 = 107.8714.01(3 ×16.00) = 169.87 g/mol.
Step 2: Calculate the grams of tableware nitrate needed to prepare the result The formula for calculating grams is given as:
grams = normality × molar mass × volume (in liters)
Given that the normality (N) is 0.02 and the volume will be determined latterly, we can calculate the grams of AgNO3.
Step 3: Determine the volume of the result you want to prepare:
Let's assume you want to prepare 500 mL (0.5 L) of the tableware nitrate result.
Step 4: Calculate the grams of tableware nitrate demanded:
grams = 0.02 N × (169.87 g/mol) ×0.5 L = 1.6987 grams.
Step 5: Weigh out the calculated mass of tableware nitrate (1.6987 grams) using an logical balance.
Step 6: Dissolve the counted tableware nitrate in distilled water:
Take a clean, dry vessel and add distilled water. sluggishly add the counted tableware nitrate to the water while stirring continuously until it's fully dissolved. Insure that all the solid AgNO3 is dissolved.
Step 7: Transfer the result to a volumetric beaker:
Once the tableware nitrate is fully dissolved, transfer the result to a 500 mL volumetric beaker. wash the vessel used for dissolution and make sure all the result is transferred.
Step 8: Adulterate the result to the mark Add distilled water to the volumetric beaker gradationally, while swirling gently, until the bottom of the meniscus aligns with the mark on the beaker. Don't overpass the mark. Add water cautiously to reach the asked volume.
Step 9: Mix the result Cap the beaker tightly and reverse it several times to insure proper mixing of the result.
You have now prepared a 0.02 N tableware nitrate result in a 500 mL volumetric beaker.
Flash back to handle tableware nitrate with care as it's poisonous and can beget stains. Also, be conservative when using dinnerware and follow proper laboratory safety practices.
Hers, remember that the valency is 1, the molarity and normality of the AgNO3 results are the same.
