Question

The arrow pointing downwards $(\downarrow )$ along with a product represents a gaseous product, whereas the arrow pointing upwards $(\uparrow )$ represents the precipitate in a reaction.

• A. True
• B. False

Answer 1

The correct option is B False

The arrow pointing downwards $(\downarrow )$ along with a product represents a precipitate of a chemical reaction. For example:
${\text{AgNO}}_3\text{(s)}+\text{NaCl(aq)}\to \text{AgCl (s)}(\downarrow )+{\text{NaNO}}_3\text{(aq)}$

The arrow pointing upwards $(\uparrow )$ represents the gaseous product of a chemical reaction. For example:
${\text{CaCO}}_3\text{(s)}\stackrel{△}{\to }\text{CaO(s)}+{\text{CO}}_2\text{(g)}(\uparrow )$

Hence, the given statement is false.
