Assertion (A) is correct. The main product formed by the reaction of zinc with sodium hydroxide is sodium zincate. Reason (R) is incorrect. Zinc can displace sodium from its solution, and the reaction between zinc and sodium hydroxide results in the formation of sodium zincate.
Zinc is a transition metal that has less reactivity than sodium metal thus it could not displace sodium from sodium hydroxide. When bases react with metal, they produce a metallic salt and release hydrogen gas. When Zinc (Zn) reacts with Sodium hydroxide (NaOH) it shows the following reaction: Zn + 2 NaOH → Na₂ZnO₂ + H₂
(c) Sodium sulfate is a salt and it is formed when sulfuric acid reacts with sodium hydroxide. This is commonly used in detergents and the manufacturing of paper and textiles. Zinc oxide which is the fourth option provided is an amphoteric compound. This means it can exhibit both acidic and basic properties depending on the circumstances.
Answer: Add more hydroxide (NaOH). The zinc will form the zincate (Zn (OH) [math]_4^ {2-} [/math]) and go into solution leaving the magnesium hydroxide untouched. If you filter off (or simply decant) the liquid containing the zinc, all you will have left is solid magnesium hydroxide. If you want to recover the zinc, just acidify the decanted ...

Zinc hydroxide Zn(OH)2 is an inorganic chemical compound. It also occurs naturally as 3 rare minerals: wülfingite (orthorhombic), ashoverite and sweetite (both tetragonal). Like the hydroxides of other metals, such as lead, aluminium, beryllium, tin and chromium, zinc hydroxide (and zinc oxide), is amphoteric.

correction- there is no such acid called hydroxide acid, i think you meant hydrochloric acid. zinc + hydrochloric acid —> zinc chloride + hydrogen gas Zn + HCl —> ZnCl2 + H2
Answer: Zn (NO3)2 + 2NaOH = Zn (OH)2 + 2NaNO3. Explanation: Advertisement. archana9999. Explanation: It is generally accepted that zinc hydroxide nitrate with the ideal composition Zn5 (OH)8 (NO3)2. 2H2O can be prepared by precipitation from a solution of Zn (NO3)2. 6H2O with NaOH (OH/Zn ratio 0.5) at room temperature with vigorous stirring.
