Question

what happens when aqueous solution of lead acetate and sodium sulphide are mixed each other​

Answer 1

Answer:

Explanation:

(a) A black precipitate of lead sulphide is formed.

Na2S+(CH3COO)2Pb→PbS(Black ppt)+2CH3COONaSod. AcetateLead acetate

(b) The solution acquires a violet colour.

Na2S+Na2[Fe(CN)5NO]Sod. nitroprusside→Na4[Fe(CN)5NOS](violet colour)

(c) The oily layer of CS2 acquires a violet colour. chlorine being more reactive than iodine displaces the same from the salt solution

2NaI+Cl2→2NaCl+I2

(d) Sodium phosphate is formed on fusion.

5Na2O2+2P−→−(Fuse)2Na3PO4+2Na2OSod. phosphate

Answer 2

When the aqueous solution of lead acetate and sodium sulphide are mixed with each other​, then a black precipitate of lead sulphide is formed along with sodium acetate.

- A double displacement reaction takes place when Lead Acetate ((CH3COO)2Pb) reacts with Sodium Sulphide (Na2S).

- The products formed in this reaction are black ppt of PbS along with CH3COONa.

- The balanced chemical reaction is given as:

Na2S + (CH3COO)2Pb → PbS + 2CH3COONa
