chromate is sparingly soluble in aqueous solutions. The Ksp of Ag2CrO4 is 1.12×10−12 . What is the solubility (in mol/L) of silver chromate in 1.00 M potassium chromate aqueous solution?

Explanation:

For this question, we have to start with the ionization equation for , so:

With this in mind we can write the Ksp expression:

Additionally, for every mole of  formed, 2 moles of are formed. We can use "X" for the unknown concentration of each ion, so:

 and  

Now, we can plug the values into the Ksp expression:

Now we can solve for "X" :

I hope it helps!

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6

the answer is minerals.
