Answer:
Molarity of silver ion: 0.296 M
Explanation:
Reaction:
AgNO₃ + KCl → AgCl↓ + K⁺ + NO₃⁻
From the reaction, we know that the moles of AgCl produced will be the same as the moles of initial silver.
First, let´s calculate the number of moles of AgCl produced:
1.56 g AgCl was produced, that is, (1.56 g AgCl * 1 mol AgCl/143.3 g AgCl) 0.011 moles AgCl.
The moles of silver ion present in the original solution was 0.011 mol. Since this number of moles was present in a 37.1 ml solution, then, in 1000 ml:
moles of silver ion per liter = 1000 ml * 0.011 mol / 37.1 ml = 0.296 mol
Molarity of silver ion = 0.296 M
