We are asked a few analytical chemistry questions here.
00:05
The first question, y4 minus is the anion for what reagent? this is the anion for edta, and ebta is the short name.
00:20
The full name is ethylene, diamine, tetracycetic acid.
00:38
And as you can probably tell by the name, this is a very large molecule.
00:41
So y is used as the universal abbreviation.
00:53
What is the mass of hydrochloric acid needed to prepare 0 .001 molar of hcl solution, the hydrochloric acid solution? so this is the same as 1 millimolar.
01:06
But we can just use the standard molar convention.
01:11
So 0 .001 molar is equal to.
01:18
0 .001 moles per liter of solution.
01:26
One mole of hydrochloric acid is approximately 36 grams...
