That sounds as if you have written instructions for two preps; i.e., one at boiling T for water and the other at room T. Either should be adequate. With the first one, you will get crystallization when the solution cools.
Take a cup of water, add sugar, and stir. If the resulting solution contains sugar crystals that do not dissolve, the solution is said to be? a)an unsaturated solution b)a saturated solution c)a homogeneous solution d)none of the
A teacher prepares a saturated NaCli solution at 55 Degree C. What is the % by mass 9m/m0 of this solution? what is the concentration of this solution expressed in ppm? What is the molality of this solution? If the density of the
PLEASE SHOW PROCEDURE! You wish to prepare an aqueous solution that has a freezing point of -0.100 degrees Celsius. How many milliliters of 12.0 M HCl would you use to prepare 250.0 mL of such a solution? [Hint: Note that in a
Which of the following solution has greater density? 1. 100ml of saturated aqueous solution of Lif. (Ksp(Lif)=1.84*10^-3). 2. 100ml of saturated aqueous solution of Hg2F2. (Ksp(Hg2F2)=3*10^-6). (We can assume that adding the
I'm trying to find the solubility of Ca(OH)2 in .0125 mol/L aqueous NaOH. Here is my data: Vol of solution used per titration: 20mL Conc of HCl: .1201 mol/L Average Titre: 4.71 I need to calculte: 1. the TOTAL [OH-] in the
Aqueous ammonia is typically sold by chemical supply houses as the saturated solution, which has a concentration of 14.5mol/L. What volume of NH3 at STP is required to prepare 100. mL of concentrated ammonia solution?
