Question

Chemical name for ${\mathrm{Na}}_2{\mathrm{PbO}}_2$

Answer 1

Acid-base reactions:

1. An acid reacts with a base to produce salt and water in an acid-base reaction.
2. The pH of these types of reactions is usually $7$
3. It is classified into four types depending on the nature of acid and base i.e. Strong acid-Strong base, Strong Acid-Weak base, Weak acid-Weak base, and Weak acid-weak base.
4. The given chemical compound i.e. ${\mathrm{Na}}_2{\mathrm{PbO}}_2$is a result of a neutralization reaction that takes place between Lead oxide and Sodium hydroxide.
5. Lead oxides are amphoteric meaning they dissolve in water under acidic and basic conditions.$\underset{\mathrm{Lead}\mathrm{oxide}}{\mathrm{PbO}\left(\mathrm{s}\right)}+\underset{\mathrm{Sodium}\mathrm{hydroxide}}{2\mathrm{NaOH}\left(\mathrm{aq}\right)}\to \underset{\mathrm{Sodium}\mathrm{plumbite}}{{\mathrm{Na}}_2{\mathrm{PbO}}_2\left(\mathrm{s}\right)}+\underset{\mathrm{Water}}{{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)}$
6. Here, lead oxide act as an acid, and sodium hydroxide is a base.
7. Sodium oxide reacts with Lead oxide to produce Sodium plumbite

Therefore. chemical name for ${\mathrm{Na}}_2{\mathrm{PbO}}_2$ is Sodium plumbite.
