Question

A 5.00 mL of a salt solution of unknown concentration was mixed with 35.0 mL of 0.523 M AgNO3. The mass of AgCl solid formed was 0.508 g. _AgNO3 (aq) +_NaCl (aq)AgC1(s) _NaNOs (aq) What is the chemical term for the silver chloride solid that is formed? Select one: O A. Bubbles B. Barnacles C. Precipitate D. Solubles E. None of these terms

Answer 1

Answer:

The silver chloride solid that is formed, is a Precipitate (Option C)

Explanation:

AgNO3 (aq)  +  NaCl(aq)  →  AgCl(s) ↓  + NaNO4 (aq)

AgNO3 (aq) → Ag⁺(aq)  +  NO3⁻(aq)

NaCl(aq) →  Cl⁻ (aq) + Na⁺(aq)

Ag⁺(aq) + Cl⁻(aq) →  AgCl (s)↓

In the presence of chlorides, the silver cation binds to the anion through an ionic bond to generate the salt, which is an insoluble solute
