1. Briefly explain why it is essential that there be some solid Sr(IO3)2 present in the bulb of the reaction pipet when the equilibrated supernatant liquid is measured, prior to titration.
I did not do any experiments or anything for this, so I don't understand how to answer this. Please help me!
Homework Answers
The reason to have some solid sample left in any solubilization experiment is to have a saturated solution.
A saturated solution is one where the solute has completely dissolved and no more solute can dissolve this is indicated by some solid being insoluble.
I am assuming you are using a saturated solution for some titration where you need this to be saturated so the indication is some solid Sr(IO3)2

So in my house, I have a bathroom to myself, and a while ago the toilet roll holder broke when my nephew was using the bathroom. Instead of buying and installing another one I simply use a twisted clothes hanger. The Hanger is twisted in a U shape so the toilet paper roll can be used on it.

For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2
For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2....the problem is that if I don't boil it for that long and (30 min) b/c of not enough time but I put the water I boiled for 1/2 hr aproximately into a NaOH bottle with a CO2 absorber and stored it there for a few days. I would assume that I would have to boil the water again...but...
