SODIUM HYDROXIDE

When sodium borohydride is in a strongly basic solution (at or above pH 10) it is stabilized against reaction with water although addition of water may still be exothermic due to heat of solvation At lower pH levels sodium borohydride reacts exothermically with water to generate flammable hydrogen gas The heat may ignite the hydrogen the

Can you use sodium hydroxide to make soap?

Sodium Hydroxide is also used to hydrolyze fats (as in saponification) and form soaps It is also known as caustic soda and soda lye Sodium Hydroxide is a strong alkaline substance that dissociates completely in water to sodium and hydroxyl ions This creates a strong exothermic reaction when it is added to water
