What concentration of clo3– results when 925 ml of 0.393 m agclo3 is mixed with 685 ml of 0.283 m mn(clo3)2?
docker41 [41]

Answer;

= 0.7698 M

Explanation and solution;

AgClO3 ionizes as follows:  

AgClO3 ---> Ag^+ + ClO3^-  

Moles AgClO3 dissolved ---> (0.393 mol/L) (0.925 L) = 0.424865 mol

From the chemical equation, one mole of AgClO3 dissolving yields one mole of ClO3^- in solution.

Moles ClO3^- = 0.424 865 mol

Similarly;

Mn(ClO3)2 dissolves as follows:

Mn(ClO3)2 ---> Mn^2+ + 2ClO3^-

Moles Mn(ClO3)2 dissolved ---> (0.283 mol/L) (0.685 L) = 0.413139 mol

From the chemical equation, one mole of Mn(ClO3)2 dissolving yields two moles of ClO3^- in solution.

Moles ClO3^- = 0.413139 mol x 2 = 0.826277 mol  

Total moles ClO3^- in solution;

0.826277 mol + 0.413139 mol = 1.239416 mol  

Total volume of solution ---> 0.925 L + 0.685 L = 1.61 L  

Molarity of ClO3^- ---> 1.239416 mol / 1.61 L = 0.7698 M
