# What is the name of the salt product formed from a neutralization reaction between butanoic acid and sodium hydroxide?

sodium butanoate

#### Explanation:

the net ionic equation for neutralisation is ${H}^{+} + O {H}^{-} \rightarrow {H}_{2} O$.

this is because the hydrogen ion dissociates from the acid, and the hydroxide ion dissociates from the metal hydroxide.

the neutralisation reaction forms a metal salt and water.

since the ${H}^{+}$ and $O {H}^{-}$ form ${H}_{2} O$, the formula of the salt is the formula of the acid minus a hydrogen ion, and the formula of the metal hydroxide minus the hydroxide ion.

the acid is $C {H}_{3} C {H}_{3} C {H}_{2} C O O H$. without a hydrogen ion, this is $C {H}_{3} C {H}_{3} C {H}_{2} C O O$.

the metal hydroxide is $N a O H$. without a hydroxide ion, this is $N a$.

the symbol for the metal salt is given by adding the symbol for the ionised metal to the symbol for the ionised acid.

hence, the symbol is $C {H}_{3} C {H}_{3} C {H}_{2} C O O N a$, or $N a \left({C}_{3} {H}_{7} C O O\right)$.

its IUPAC name is sodium butanoate.
