Write the net ionic equation, including phases, that corresponds to the reaction Pb(ClO )2(aq) + Na, S(aq) Pb(s) + 2 NaCIO, (aq) net ionic equation:

Answer 1

Steps we follow to write a net ionic equation are:

1. Balance the chemical equation.

2. Break the aqueous species into their corresponding ions and the solid, liquid and gas phase species remain unchanged.

3. Cancel out the spectator ions( ions that are present on both the reactant and the product side).

This is shown in the attached figures.

Given chemical reaction : Poleronda (aq) + Nags (aq) PbS(s) + 2Nacion (aq) for writing a net bonic equation, the steps we need to do are: 1) Balance the chemical equation. - In this case, Left hand side Right hand side Pb Pb م 2 Nasz Na is II aloyna Since, same number of species Catons) are present on both side of the equation therefore, the reaction is balanced. 2) we need to write the equation in terms of all the ions present in the solution. for this only the reactants and products which are present in aqueous medium will dissociate into their corresponding ions. Therefore, complete ionic equation is: Pb2+ (aq) + 2 con cap) Pb(s) + anatcaq). + znacajt s²(aq) +zaou (aq)

3) In order to deduce the complete ionic equation to its corresponding net ionic equation, we . caned out those ions which are present both on the reactant side and the product side (these ions are called spectator cons) Complete ionic equation: Abit eam) + 2 chicag) + znatlaq) + szcaq) → PbSC) & znat(aq) +7 одоо ) In this case, zuloj (aq) and anatcaq) are the spectator ions. ... The net ionic equation is: و ۴ (حى حمام (مه او دا د
