Metal corroding in salt water corrosion is a chemical change
One molecule of nabh4 will reduce only two molecules of m-acetylbenzaldehyde to form the corresponding product because there are only two functional groups that can react with NaBH4, namely the ketone and the aldehyde, but NaBH4 had four H present to protonate the molecule.
What is protonation?
An atom, molecule, or ion can be protonated by adding a proton to it. The difference between protonation and hydrogenation is that during protonation, the protonated species' charge changes, whereas it remains unchanged during hydrogenation. Numerous catalytic processes result in protonation.
A conjugate acid is created when a proton (or hydron, or hydrogen cation), (H+), is added to an atom, molecule, or ion. Deprotonation is the analogous process that occurs when a proton is taken out of a Bronsted-Lowry acid.

HCl + NaOH = NaCl + H₂O
H₂SO₄ + 2NaOH = Na₂SO₄ + 2H₂O ⇒ <span>0.5H₂SO₄ + NaOH = 0.5Na₂SO₄ + H₂O
V(HCl)=2V(H₂SO₄)
</span><span>The volume of the hydrochloric acid solution (HCl) is twice as large as the volume of the sulfuric acid solution (H</span>₂SO₄)<span>.

Acids are acids and alkalines are alkalines.
It is an example of a Chemical change.
