Question

A double-replacement reaction takes place when aqueous cobalt(iii) chloride reacts with aqueous lithium hydroxide. one of the products of this reaction is _____.

Answer 1

the correct answer is Co(OH) 3

Answer 2

Answer: Cobalt hydroxide as solid and Lithium chloride in aqueous solution.

Step-by-step explanation:

A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.

The reaction between cobalt (iii) chloride and lithium hydroxide is:

`CoCl_3(aq)+3LiOH(aq)\rightarrow Co(OH)_3(s)+3LiCl(aq)`

Thus cobalt hydroxide is formed as a precipitate and Lithium chloride is formed in aqueous solution.
