Sodium aluminate is also used in the paper industry, for fire brick production, alumina production and so forth. That being said, upon looking at the reaction between aluminum oxide and sodium hydroxide it appears water is formed in place of hydrogen gas. The reaction is exothermic. Al is amphoteric in nature, so it can react with both acid and base. The resulting bond between the sodium and the ethanoate group is ionic. Sodium metal reacts rapidly with water to form a colourless solution of sodium hydroxide (NaOH) and evolve hydrogen gas (H2).
