Question

a student mixes 1.0 ml of aqueous silver nitrate, $ce{agno_{3}(aq)}$, with 1.0 ml of aqueous potassium chloride, $ce{kcl(aq)}$, in a clean test tube.
what will the student observe? select the single best answer.
○ the mixture appears to be white and cloudy.
○ the mixture will remain colorless and transparent, but the test tube will feel hot.
○ bubbles will form within the liquid mixture.
○ a silver mirror will coat the interior of the test tube.
○ the mixture will remain colorless and transparent.

Explanation:

When aqueous silver nitrate ($\text{AgNO}_3$) reacts with aqueous potassium chloride ($\text{KCl}$), a double displacement reaction occurs. The chloride ions ($\text{Cl}^-$) combine with silver ions ($\text{Ag}^+$) to form insoluble silver chloride ($\text{AgCl}$), a white precipitate that makes the mixture appear cloudy.

Answer:

The mixture appears to be white and cloudy.
