KBr (aq) + AgNO3 (aq) → KNO3 (aq) + AgBr (s)

In the chemical reaction above, what state is KBr in?

a

Solid

b Aqueous

C Liquid

d Gas

B Aqueous

Explanation:

We are given the equation;

KBr (aq) + AgNO₃ (aq) → KNO₃ (aq) + AgBr (s)

The equation shows a precipitation reaction or a double displacement reaction. Precipitation reaction because two soluble salts reacts to produce a precipitate as one of the product. Double displacement reaction because the salts exchange cations and anions to form new compounds In the equation; KBr is in aqueous state since all salts of potassium (K) are soluble in water. KNO₃ and AgNO₃ are also in aqueous state as all nitrates are soluble in water. AgBr on the other hand is in solid state since its a precipitate that is insoluble in water.
