Equal volumes of what concentrations of AgNO₃ and HCl should be mixed to form a AgCl precipitate? [Ksp for AgCl = 10⁻¹⁰]

Question

Vimal Swarnkar · Accepted Answer

(d) 10⁻⁴ M AgNO₃ and 10⁻⁵ M HCl. Equal volumes halve each concentration. Need ionic product > Ksp = 10⁻¹⁰. (a) 5×10⁻⁵ × 5×10⁻⁸ = 2.5×10⁻¹²; (b) 2.5×10⁻¹¹; (c) 2.5×10⁻¹³; (d) 5×10⁻⁵ × 5×10⁻⁶ = 2.5×10⁻¹⁰ > 10⁻¹⁰ → precipitate → (d).

Answer

(a) 10⁻⁴ M AgNO₃ and 10⁻⁷ M HCl

Answer

(b) 10⁻⁵ M AgNO₃ and 10⁻⁶ M HCl

Answer

(c) 10⁻⁶ M AgNO₃ and 10⁻⁶ M HCl
