When you put zinc chloride in sodium hydroxide solution, sodium chloride and zinc hydroxide are formed. ZnCl2 + 4NaOH → Na2[Zn(OH)4] + 2NaCl. Zinc chloride react with sodium hydroxide to produce sodium tetrahydroxozincate(II) and sodium chloride. Sodium hydroxide - concentrated solution. read more
zinc reacts with sodium hydroxide to form sodium zincate and hydrogen gas ie. 2NaOH + Zn -> Na2Zno2 +H2 (atomicity should be written in the right corner of the element). read more
Like the hydroxides of other metals, such as lead, aluminium, beryllium, tin and chromium, zinc hydroxide (and zinc oxide), is amphoteric. Thus it will dissolve readily in a dilute solution of a strong acid, such as HCl, and also in a solution of an alkali such as sodium hydroxide. read more
