sodium butanoate

Explanation:

the net ionic equation for neutralisation is #H^+ + OH^(-) rarr H_2O#.

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 #OH^-# form #H_2O#, 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 #CH_3CH_3CH_2COOH#. without a hydrogen ion, this is #CH_3CH_3CH_2COO#.

the metal hydroxide is #NaOH#. without a hydroxide ion, this is #Na#.

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 #CH_3CH_3CH_2COONa#, or #Na(C_3H_7COO)#.

its IUPAC name is sodium butanoate.
