Question

which solution will give a gelatinous white precipitate with zinc sulphate solution?
​

Answer 1

Answer:

Sodium hydroxide solution NaOH can be used to identify Zn2+ since its addition to zinc carbonate solution will give white gelatinous precipitates of Zn(OH)2 which are soluble in excess of NaOH. Write equation for the reaction that will take place when copper sulphate solution is added to sodium hydroxide solution.

Answer 2

Answer:

if u like it mark me as brainlist

Explanation:

NaOH reacts with ZnSO 4 to form a white gelatinous precipitate of zinc hydroxide (Zn (OH) 2) which is soluble in excess of NaOH. ZnSO 4 reacts with H 2 S to form a white precipitate of zinc sulphide (ZnS). Zinc metal is more reactive than hydrogen. This is a single displacement reaction of a non-metal by a metal.
