What does it mean if a drug has solvent instability or not dissolve in solution
what does it mean by incipient of instability (GM = 0)? can you explain "to identify loading conditions for incipient of instability for GM = 0 in metancentric height experiment?
You dissolve an amount of solid Q in 215.0 mL solvent, forming an unsaturated solution. The solubility of Q at 0°C is 1.07 g/100 mL. The amount of solid remaining in solution at 0°C is 21.0% of the original amount of solid dissolved (Side question - what is the % recovery?). What is the original amount of solid that was dissolved (report to 1 decimal place)?

0 3) You have to use as little solvent as possible to dissolve a solute to create a saturated solution. Assuming that you are using an ideal solvent, what should you do to the solvent and solute BEFORE adding the solvent to the solute to achieve the forming of a saturated solution? (4 pts) to a Solvent:
What does it mean if a solvent in an experiment (methanol) is chilled to transfer and wash products v. if it is at room temperature
why is it important to use a minimum volume of hot solvent to dissolve an impure sample during recrystallization and why is it advisable to cool the solution of a mixture slowly during recrystallization?
1. A solution generally consists of two parts, a solute that is dissolved and a solvent that the solute is dissolved into. For example, sugar is a solute that is dissolved into the solvent water. In the Solubility and Temperature Gizmo, you will study how temperature affects how much solute will dissolve in a solution To begin, check that Potassium nitrate is selected, and the Temp. of the water is 20 °C. a. In this solution, what is the solute?...
AgCl does not dissolve well in aqueous solution with most of the compound precipitating to the bottom of the container and small amounts dissolving in the solution. If the chloride ions that are present in solution could be removed selectively, what would happen to the concentration of the silver ion in the solution? Select one a. nothing b. impossible to determine without knowing the initial concentrations • Cincrease d. decrease Gear my choice
You dissolve 7.1 g of compound X (molar mass = 151.6 g/mol) in 1.62L of solvent Y, which has a density of 0.90 g/mL. What is the molality?
If the partition coefficient of a drug between an organic solvent and water is 5, how many mg of the drug is extracted from a 120 ml of 2% aqueous solution if it was extracted with 60 ml of the organic let mass of compound insolution = 4mg
Why does a substance with a endothermic heat of solution dissolve (for example Sodium acetate trihydrate)
