Hi
Please tell me quikest way to dissolve 1m Sodium Fluoride & 1m Barium Nitrate. I am heating them too.

Barium nitrate 1M won't dissolve. I think the maximum is about 10% (approx 0.4M)solution. I have only made up 0.1M Sodium flouride, so don't have an answer for that one, I'm sorry.

The solubility of sodium fluoride is 4.1g/100ml and a 1M solution is 42g/1000ml so you are virtually making a saturated solution with heating you may get it to dissolve but it may come out of solution once it cools down.

Barium nitrate the solubility is 10.1g/100ml and to make a 1M solution you would need 261.3g/1000ml or 26.1g/100ml so it will never dissolve.

Hope this helps you out!!
