Answer 1

Answer #1

Q:1. Ans :- FALSE, Because the reaction between Co (II) ion and hydroxide ion gives the precipitates of Co(OH)₂ (s) which are insoluble in water. That is :

Co²⁺ (aq) + 2 OH^- (aq) ----------------> Co(OH)₂ (s)

--------------------

Q:2. Ans :- The solubility rules for halides is :

Chlorides (Cl^-), Bromides (Br^-) and Iodides (I^-) are soluble in water, except those containing Ag⁺, Hg²⁺ and Pb²⁺ are insoluble.

-------------

Q:3. Ans :- Reaction is :

CO₃^2- (aq) + HCl (aq) ---------------> HCO₃^- (aq) + Cl^- (aq)
