The unknown aqueous substance is MgBr2
Mg + PbBr2 → MgBr2 + Pb
1 mole of Magnesium [Mg] reacts with 1 mole of Lead(Ii) Bromide [PbBr2] to form 1 mole of Magnesium Bromide [MgBr2] and 1 mole of Lead [Pb]. It is a single displacement substitution reaction
What is displacement reaction ?
One element in a compound is replaced by another in a single-displacement reaction, sometimes referred to as a single replacement reaction or exchange reaction.
- Here are two instances of displacement reactions: the process by which iron and copper sulphate react to produce iron sulphate as a byproduct. Because iron is more reactive than copper in this situation, copper is replaced. Zinc and iron sulphate react, producing zinc sulphate as a byproduct.
