Sodium react with water forming a base - sodium hydroxide - and releasing hydrogen. Add an acid for neutralization.
No, adding solid sodium hydroxide to neutralize hydrochloric acid (HCl) would not cause sodium chloride to redissolve. The reaction between sodium hydroxide and hydrochloric acid forms water and sodium chloride, which remains in its dissolved form. The addition of solid sodium hydroxide would simply further neutralize the acid and increase the concentration of the resulting sodium chloride solution.

You can neutralize bleach (Sodium Hypochloride) with Sodium sulfite (chemical formula Na2SO3), Sodium metabisulfite, Hydrogen peroxide, or white vinegar (3% acetic acid (CH 3 CO 2 H) and water). On occasion, I've used the juice from a lemon, added to water. Any mild acid will neutralize a weak base of a working bleach solution used as a germicidal agent.

Strong base is added to neutralize the strong acid (H2SO4).
Soda ash, i.e. Sodium carbonate or its bicarbonate
There are times when bacteria, acidify an infected site, therefore adding sodium hydroxide will neutralize the region for a basic site.
Sodium bicarbonate gives hydrogencarbonate ions which can produce carbondioxide and water with protons. It acts as a weak base.
Sodium hypochlorite is dissociated in water.
You will obtain a sodium chloride solution in water.
Sodium is an unstable element which reacts violently when in contact with water. Sodium added to water can result in explosions.
if cyclohexene is prepared by dehydration of cyclohexanol in the presence of a strong acide like H3PO4, sodium carbonate will be used to neutralize the acidic medium
