Questions:
Is sodium zincate a salt?
Sodium Zincate is considered a salt because it forms an ionic compound through the reaction of a metal (Zinc) and a base (Sodium Hydroxide). Electrostatic forces hold positively charged Zinc ions and negatively charged Sodium and Hydroxide ions together. Salts are ionic compounds formed from the reaction between an acid and a base or a metal and a non-metal. Although Na2Zn(OH)4 does not result from the reaction of an acid and a base, it still meets the general definition of a salt as an ionic compound.
