Dissolve 1 tablespoon (17 grams) of salt in 1.24 cups (290 mL) of water. Add the water to a glass and gently pour the salt into the water. Stir it in well with a spoon until the salt is completely dissolved. If your cup has a lid, attach it after adding the salt and shake it up and down to mix the salt it in.
How is sodium hydroxide made?
Sodium hydroxide is derived from salt water (brine). It is most commonly manufactured by the electrolysis of brine, a salt (NaCl) solution. During this process the water (H20) is reduced to hydrogen gas (H) and hydroxide ion (OH). The hydroxide ion bonds with the sodium to form sodium hydroxide (NaOH).
How can we make caustic soda at home?
Caustic soda (usually as NaOH) is produced as a liquid. These are produced by passing an electrical current through brine (common salt dissolved in water). This is called electrolysis, a process which has been known for over 120 years.
