Can you please look up "Table 4.1 Solubility Guidelines for Common Ionic Compounds in Water" and explain why the diffference in solubility for CaSO4, AgSO4, and Ca(OH)2. I saw the solubility table showed slightly soluble for the first 2 and the last one is a strong base of group 2A metal hydroxides. I just need closure on the matter of why not soluble?
@quandaledingle-zm5pmАй бұрын
Dr., at 8:45, the exceptions for oh- seem to be wrong, since earlier ca(oh)2 was said to be insoluble but now it's soluble according to the table

Hmmmm. Group 1 elements (Li, Na, K) and NH4+ are almost always soluble. So compounds with these should be soluble according to the solubility rules.

PbI2 is one of those exceptions. If you see Pb or Ag be careful! Check the rules in the video. You'll see it Pb there.

So some rules says “all metals” but what if some had non metals in it. Like rule 3. If nitrate had a non metal with it, is it soluble?
@wbreslyn3 жыл бұрын
I would suppose so. NH4NO3 certainly would be. But since the nitrate ion has a 1- ionic charge it doesn't bond with non-metal ions which are negative.

@mikeboyd19612 жыл бұрын
Group 1 always soluble because their charge is only 1+. Once you get 2+, 3+ and greater the solubility decreases. More charge means stronger ionic bonding and lower solubility. Similarly for the anions. Halides generally soluble as 1-. CO3 2- & PO4 3- generally insoluble except when with monovalent cations ie group 1 and the ammonium ion. NOW you are going to ask what about OH- ion which seems to be an exception. I think this is partially down to charge to mass ratio but am guessing a little. Mol wt OH- is 17. Cl- 35.5, CO3 2- 60, PO4 3- 95. I am fairly sure that there will be other effects as well. Quantum effects and Nuclear Resonance Effects maybe? We need more help from the experts!
That is a good question! I don't think I ever made that video (I'll put it on my list). But this video might be of help: kzbin.info/www/bejne/qZ_boJidr7uhjdk
