I am using a release agent for polyurethane resin moulded parts.
The release agent is a solution of silicone (oil?) in Heptane, Petroleum Naptha and an Aliphatic Solvent.
I'm new here, I have a simple question.
Is IsoPropyl Alcohol a good solvent for vitamin A??
Is IsoPropyl Alcohol a good solvent for Vitamin D??
And is IsoPropyl Alcohol a good solvent for Vitamin E??
I dont like working with ethyl alcohol because you need a license to purchase.
I'll consider this a high-school level inquiry because my "vast" *g* chemistry background was neither put to regular use nor has been recalled to mind several decades later. So... please have some patience. TIA.
The issue: I bought a small amount of gold leaf paint that is Xylene...
1.) If i make a solution by adding 83grams of sodium hydroxide to
750 mL of water..
a) what is the molality of NAOH in this solution?
b) what is the percent by mass of NAOH in this solution?
C) what is the mole fraction of NAOH
2) Explain how you would make 450 mL of a 0.25M Calcium chloride...
help! i think i used the wrong solvent in my first experiment! the isopropyl alchohol didnt fully dissolve my vacuum filtrate of testosterone propionate and estradiol benzoate mixture. i need to run a column and would love to know what is the proper solvent so i dont have to purchase a bunch of...
I have a chemistry exam tomorrow, and while I was studying I came across a problem that was unknown to me.
A solution has a density of 1.18 g/mL and a volume of 625 mL. The solution contains 30.0 grams of CaCl2. How many grams of solvent are present?
I have found the molarity of the solution...
Suggest a suitable solvent for the dilution of ethanol.
(solvent is not water since it reacts with ethanol to form an acid, earlier parts of the question involves sodium as one of the reagents. I need a solvent which doesnt reacts with ethanol)
