A student combines solutions of silver nitrate, $A g N O_{3}$ $AgNO_3$ , and sodium chromate, $N a_{2} C r O_{4}$ $Na_2CrO_4$ , and observes that a reddish-brown solid forms. Based on this observation, what type of a reaction can the student infer has occurred?

A metathesis, or partner exchange reaction has occurred:

Explanation:

$2 A g N O_{3} (a q) + N a_{2} C r O_{4} (a q) \to 2 A g N O_{3} (a q) + A g_{2} C r O_{4} (s)$ $2AgNO_3(aq) + Na_2CrO_4(aq) rarr 2AgNO_3(aq) + Ag_2CrO_4(s)$

Most silver salts are quite insoluble; the nitrate is an exception. Silver chromate precipitates from aqueous solution as a brick red precipitate.

The reaction could also be called a $precipitation reaction$ $"precipitation reaction"$ . This particular reaction is the basis of the $Mohr titration$ $"Mohr titration"$ , for quantitative analysis of silver ion.
