What is the concentration of nitrate ions, if equal volumes of 0.1M AgNO, and 0.1M NaCl are mixed together?mol
Correct answer: C. 0.05M
- A. 0.1M
- B. 0.2M
- C. 0.05M
- D. 0.25M
Explanation
When AgNO₃ (silver nitrate) and NaCl (sodium chloride) are mixed, a double displacement reaction occurs, leading to the formation of AgCl (silver chloride) and NaNO₃ (sodium nitrate). The balanced chemical equation is:AgNO₃ + NaCl → AgCl + NaNO₃Since both AgNO₃ and NaCl are 0.1M, they react in a 1:1 ratio, resulting in the formation of 0.1M AgCl and 0.1M NaNO₃.However, AgCl is insoluble in water and forms a white precipitate, while NaNO₃ remains in solution. Therefore, the concentration of nitrate ions (NO₃⁻) in the final solution is 0.1M - 0.1M = 0.05M

About Fundamental Concepts of Chemistry
Mole calculations connect mass, number of particles and Avogadro's number, while balanced equations provide the mole ratios used in stoichiometry. Questions cover limiting and excess reactants, theoretical yield and percentage yield, including identifying which reactant is consumed first and comparing the actual product with the maximum possible product.
