Will a double replacement reaction occur if a potassium hydroxide solution is mixed with a lead(ii) nitrate solution? briefly explain.

Explanation:

A chemical reaction equation that contains same number of atoms on both reactant and product side is known as a balanced chemical reaction equation.

And, when positive and negative ions of the two reactant species exchange their position then this type of reaction is known as double replacement reaction.

For example,

Here, number of reactant molecules are as follows.

K = 1

OH = 1

Pb = 1

= 2

Number of product molecules are as follows.

K = 1

OH = 2

Pb = 1

= 1

Hence, to balance this equation multiply KOH by 2 on reactant side and multiply by 2 on product side.

Therefore, the balanced chemical reaction equation is as follows.

Since, both positive and negative ions on the reactant side get exchanged. Hence, it is a double replacement reaction.
