Question

Write the balanced chemical equation for each of the reactions. Include phases. When aqueous sodium hydroxide is added to a solution containing lead(II) nitrate, a solid precipitate forms.

Answer 1

The balanced chemical equation for aqueous sodium hydroxide being added to a solution containing lead(II) nitrate and a solid precipitate being formed is :

2 NaOH (aq) + Pb(NO3)₂ (aq) ⇒ Pb(OH)₂ (s) + 2 NaNO₃ (aq)

A balanced chemical equation is the one in which the number of atoms are equal for every element on both the the reactant side as well as the product side. Their charges should also be the same.

A precipitate is a solid mass of some substance that forms up in a liquid solution due to certain chemical reactions. This solid mass does not dissolve in the liquid solution.
