Answer:
Explanation:
AlCl₃ ⇒Al⁺³ + 3Cl⁻¹
.01M 3 x .01 M
So .01 M AlCl₃ will give 3 x .01 M Cl⁻¹
MgCl₂ ⇒ Mg⁺² + 2Cl⁻¹
.05 M 2 x .05M
.05M MgCl₂ will give 2 x .05 M Cl⁻¹
Total Cl⁻¹ formed = 3 x .01 + 2 x .05 M
= .03 + .1 M
= .13 M
AgCl ⇒ Ag⁺ + Cl⁻¹
So AgCl required = .13 M . to precipitate all chloride ions.
It is u reactive because it has to gain two electrons to have a full outermost energy level
