What evidence do you have that a water solution of K2Cr2O7 is actually an equilibrium mixture that contains [CrO4]2- ions?
Added by Mar-A G.
Step 1
K2Cr2O7, or potassium dichromate, is a chemical compound that can dissolve in water. When dissolved, it dissociates into K+ (potassium ions) and Cr2O7^2- (dichromate ions). Show more…

What is the minimum amount of water is needed to dissolve 3.0 mol potassium dichromate (K2Cr2O7)?
Supreeta N.
Some potassium dichromate $\left(\mathrm{K}_{2} \mathrm{Cr}_{2} \mathrm{O}_{7}\right), 2.335 \mathrm{g},$ is dissolved in enough water to make exactly $500 .$ mL of solution. What is the molar concentration of the potassium dichromate? What are the molar concentrations of the $\mathbf{K}^{+}$ and $\mathrm{Cr}_{2} \mathrm{O}_{7}^{2-}$ ions?
