So this is probably going to look like a ridiculously easy question, but I'm stumped. I have searched for hours looking for a formula to use, and I've given up on my text. Question: A 0.1 mol/L aqueous solution of weak monoprotic acid has a hydrogen ion concentration of 0.001 mol/L. The...

Question as posed in my text: Q: The solubility product of calcium hydroxide, Ca(OH)2, is 7.9 x 10^-6 at 25 deg. celcius. Will a precipitate form when 100mL of 0.10 mol/L of CaCl2 solution and 50.0 mL of 0.070 mol/L of NaOH solution are combined? My answer: CaCl2 = 0.10 mol/L x...

math Thanks a lot for the help, everything's clear now!

In the expression: ksp = (3.42 x 10^-7) (6.84 x 10^-7)^2 = 1.6 x 10^-19 I don't understand how the final answer is found. Can someone show me a step by step? I'm attempting to understand how to do these types of questions! Any help is greatly appreciated!

I apologize, but I don't really know what this type of math qualifies as, so it's in general math. Anyhow, it's math that's being used for equilibrium problems in a grade 12 chem course, but my math is VERY rusty... (2.5 + 2x) / (2.0 - x) = 2.50 and X = 0.56 (sorry, I wasn't sure how to...

agreed Thanks, after spending more time examining the situation, I came to the same conclusion myself. It just required some more thought I suppose.

A simple question, it would seem, but I'm missing something.. This is a question in my text. Q: Consider a stoppered flask containing benzene, iodine, and air, which has reached equilibrium at 298K. Which one of the following statements concerning the system at equilibrium is true? a)...
