Question

What ion is formed after the reaction of KBr + AgNo3 ->Kno3 + AgBr?

Answer 1

Answer:

This is a double replacement precipitation reaction. See How can the reaction KBr + AgNO3 -> AgBr + KNO3 be classified? Two soluble ionic compounds, KBr and AgNO₃, have reacted to form the insoluble compound, AgBr. The metal ions K⁺ and Ag⁺ have exchanged partners, so this is a double replacement reaction.
