Answer:
Explanation:
Given:
[AgNO3] = 0.20 M
Ba(NO3)2 = 0.20 M
[K2CrO4] = 0.10 M
Ksp of Ag2CrO4 = 1.1 x 10^-12
Ksp of BaCrO4 = 1.1 x 10^-10
Now,
So, BaCrO4 will start precipitating when [Ag+] is 4.2 x 1.2^-2 M
Reaction of copper metal with silver ion. When copper metal is placed in a solution of silver nitrate, a redox reaction forms si
1 answer:
Explanation:
The ionic reaction of the copper and the silver ions is shown below:
Copper gives up 2 electrons and transfers to 2 silver ions which gives solid silver (reduction) and copper (II) ions.
The blue color of the solution is due to the formation of copper (II) ions. The electrons in the copper ion shows d-d transition which absorbs light in the visible region and shows blue color.

Those reactions in which Alkyl Halide reacts with the solvent without the involvement of any acid or base is called as Solvolysis. In given problem <em>tert</em>-Butyl Bromide is a tertiary Alkyl Halide and we know well that tertiary alkyl halides undergo SN¹ and E¹ elimination reaction due to the formation of stable tertiary carbocation. In given example after the formation of carbocation when Isopropyl act as nucleophile it will produce ether and when it acts as a base it will produce unsaturated compound. The reaction along with both products is shown below,
