How to Calculate Li+ Ion Concentration in Saturated Li3PO4 Solution?

AI Thread Summary
To calculate the concentration of Li+ ions in a saturated Li3PO4 solution, the solubility product Ksp of 2.37 × 10-4 is essential. One participant calculated the concentration as 0.163 M, while another suggested the correct answer is 0.0544 M. The discrepancy indicates a potential error in the latter calculation, as 0.163 M appears to be a more plausible value. Clarification on the initial concentration of lithium is sought, but it seems to be unnecessary for this calculation. The discussion highlights the importance of correctly applying the Ksp value to determine ion concentrations in saturated solutions.

Homework Statement


Lithium phosphate, Li3PO4, has a solubility product Ksp = 2.37 × 10-4. What is the concentration of Li+ ions in a saturated solution of Li3PO4?

The Attempt at a Solution



What is the initial concentration of Lithium? Or does it matter?

I got 0.163 M but answer says 0.0544 M

Without it I can't do it! Somebody please help. Thanks.

0.163 M looks OK to me, 0.0544 is three times too low (which suggests an obvious mistake).

Ok thanks for confirming.
 

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
