500 mL of a 0.1 N Solution of AgNO3
Introduction
Silver nitrate (AgNO3) is a strong electrolyte widely used in various chemical reactions, particularly in analytical chemistry and inorganic chemistry. In this article, we will explore the properties and applications of a 0.1 N solution of AgNO3.
What is a 0.1 N Solution of AgNO3?
A 0.1 N solution of AgNO3 means that 500 mL of the solution contains 0.1 equivalents of silver ions (Ag+). The normality (N) of a solution is defined as the number of equivalents of the solute per liter of solution. In this case, the normality is 0.1, which means that the solution contains 0.1 moles of silver ions per liter.
Preparation of a 0.1 N Solution of AgNO3
To prepare a 0.1 N solution of AgNO3, you need to dissolve 17.0 grams of silver nitrate (AgNO3) in 500 mL of distilled water. The calculation to determine the amount of AgNO3 required is as follows:
Molar mass of AgNO3 = 169.87 g/mol Number of moles = Normality x Volume (L) = 0.1 x 0.5 = 0.05 moles Mass of AgNO3 = Number of moles x Molar mass = 0.05 x 169.87 = 17.0 grams
Properties of a 0.1 N Solution of AgNO3
A 0.1 N solution of AgNO3 has several properties that make it useful in various applications:
- Concentration: The solution contains 0.1 moles of silver ions per liter, which is equivalent to 100 mg/mL.
- pH: The pH of the solution is slightly acidic, ranging from 5.5 to 6.5.
- Conductivity: The solution is a good conductor of electricity due to the presence of silver ions.
- Reactivity: AgNO3 is a strong oxidizing agent and can react with various substances, including chlorine, bromine, and iodine.
Applications of a 0.1 N Solution of AgNO3
