Question

When the aqueous solution of silver nitrate and sodium chloride are mixed, a________ precipitate is immediately formed.

• A. yellow
• B. white
• C. red
• D. black

Answer 1

The correct option is B white

When silver nitrate $\left(AgN{O}_3\right)$ reacts with sodium chloride $\left(NaCl\right)$ a white precipitate of silver chloride $\left(AgCl\right)$ is formed which is highly insoluble in water, along with formation of sodium nitrate $\left(NaN{O}_3\right)$.

Since $\left(AgCl\right)$ is insoluble in water it will precipitate out and $\left(NaN{O}_3\right)$ is soluble in water so it will remain dissolved in the mixture. This reaction is an example of double displacement reaction and it occurs as follows:-

$AgN{O}_3+NaCl\to AgCl+NaN{O}_3$

Hence, the correct answer is the option (B).
