Question

Write one reaction for each of the following:

Formation of a precipitate

Answer 1

Precipitate:

The substance that gets deposited at the bottom after the reaction has occurred is called the precipitate.

An example of a reaction where precipitate is formed:

When Silver Nitrate$\left({\mathrm{AgNO}}_3\right)$ reacts with Sodium chloride$\left(\mathrm{NaCl}\right)$, it gives Silver chloride$\left(\mathrm{AgCl}\right)$ as the precipitate and Sodium nitrate$\left({\mathrm{NaNO}}_3\right)$ as a product.

${\mathrm{AgNO}}_3\left(\mathrm{aq}\right)+\mathrm{NaCl}\left(\mathrm{aq}\right)\to \mathrm{AgCl}\left(\mathrm{s}\right)\downarrow +{\mathrm{NaNO}}_3\left(\mathrm{aq}\right)$
