Describe how to make 2.5 L of 0.1 M HCl solution from 12 M HCl concentrated solution and water. How do differences in polarity affect solubility? How does a molecular solid such as sugar dissolve in water? Does a strong electrolyte dissolve in water to give ions, molecules, or both? Expla...
Describe how you would prepare 250 mL of a 0.025 M HCl solution from a stock solution with a concentration of 8.00 M. Stock and Dilute Solutions: Stock solutions are solutions that have a high molar concentration and are used to make it easier to pre...
Therefore, you will need to take 0.25L of the 1M HCl solution, and dilute this 0.25L to a final volume of 1L. I hope I could help you, and have a nice day! 2 Brody Cates Follow Such a solution is usually prepared by diluting the HCl from a stock solution. Purchased concentrated...
You have a 15 M stock solution which you would like to dilute 1:5 four times. What is the final concentration of the solution in mM (millimoles)? You want to make 406 mL of a solution with a concentration of 350 g/L. How much...

How do you make 250 ml of a solution of 50% ethanol? How much water should be added to 10ml of 6 alcohol solution to reduce the concentration to 5? How many milliliters of water must be added to 350 mL of 0.840 M HCl to dilu...
Flowers:Are used to make St John’s Wort blood red infused oil. The oil can be used topically for mild burns, wounds and inflammations. Harvest just when the buds began to open on a sunny day. To tell if they are ready, press a bud between your fingers, if there’s a spurt of ...
The ice does two things. It dilutes the aqua regia as it melts and takes up the heat of dilution that is generated when aqua regia is diluted. Leaving it overnight and allowing the nitrosyl chloride to break down is tantamount to converting it into HCl. You’ll notice it will have los...
Calculate how much glucose is needed to make 500 mL of a 5% glucose solution. Solutions: In chemistry, a solution is created by dissolving a substance *the solute) in another substance (the solvent). For example, when we mix table salt (NaCl) with water, we are effect...
(NaOH or KOH) andbaking sodasolution. You can use cabbage pH paper to tell if something is an acid, a base, or neutral, but you can't get highly specific pH readings like you would using a pH meter. If the liquid you are testing is very deeply colored, you can dilute it with ...
