Question

What is the molecular and net ionic equation for the reaction between aqueous \[Pb{\left( {N{O_3}} \right)_2}\]and hydrochloric acid?

Answer 1

Hint: In chemistry, equation plays a major role. In the reaction three things are main. There is a reactant, product, and reaction condition. The reactants are always kept on the left side of the equation. The plus sign is used for more than one reactant in the chemical reaction. The right side of the reaction is always the product of the chemical reaction. The plus sign is used for more than one product in the chemical reaction. In a chemical reaction, arrows are used between the reactants and products to find the reaction direction in the equation.

Complete answer:
The molecular formula of lead nitrate is \[Pb{\left( {N{O_3}} \right)_2}\].
The molecular formula of hydrochloric acid is\[HCl\].
The chemical reaction between lead nitrate and hydrochloric acid gives the product of lead chloride and side product.
The chemical reaction for the above discussion is below,
\[Pb{\left( {N{O_3}} \right)_2} + 2HCl \to PbC{l_2} + 2HN{O_3}\]
The net ionic equation for the chemical reaction between lead nitrate and hydrochloric acid is given below,
\[P{b^{2 + }} + 2C{l^ - } \to PbC{l_2}\]

Note:
In a balanced chemical reaction wise, we predict the side product of the reaction. In some cases, we are not able to attain balance by changing the mole. In that case, we use the number of countable ions in the product and reactant side of the chemical reaction. In chemistry, the redox reaction is considered as one of the types of major reactions. In this redox reaction, two methods are used to attain a balanced chemical reaction. The ion-electron method and the oxidation number method are the methods in the balanced chemical reaction.
