If 22.0 mL of 0.10 M Ba(NO3)2 are added to 41.0 mL of 0.22 M Na2CO3, will BaCO3 precipitate? I calculated Q and Ksp and found BaCO3 will precipitate, this is correct. But I got .01 for Q and this isn't. What is Q? Show calculations.

#### Solution Preview

First, we find the amount of each solute at the instant of mixing:

0.0220 L x 0.10 mol/L = 0.0022 mol Ba(NO3)2

0.0410 L x 0.22 mol/L = 0.0090 mol Na2CO3

Next, we find the molarity of ...

#### Solution Summary

This solution is provided in 195 words. It calculates amount of solute in the reaction as well as their molarity. Concentration is also used to determine the reaction quotient and solubility product constant.
