0.10 m potassium chromate is slowly added to a solution containing 0.20 m agno3 and 0.20 m ba(no3)2. what is the ag+ concentration when bacro4 just starts to precipitate? ksp for ag2cro4 and bacro4 are 1.1 × 10-12 and 1.2 × 10-10, respectively.

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

you did not give any options thus this is the best answer i can give to you with this little information you have given

> they are both natural and not man made

> they can be tracked and predicted by the right tools

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
