100
These are 4 ways to speed up dissolving a sugar cube.
What are stirring, crushing, higher temps, and more solvent?
100
This happens to molarity if more liters of solvent are added to the solution.
What is a decrease in molarity?
100
This is the type of solution you have after adding 20g of KClO3 to 100g of water at 20°C
What is a saturated solution?
100
This catches and gathers excess solute to speed up precipitation.
What is a nucleation point?
200
This is a particle diagram that shows one mole of CH3OH fully dissolved, including the water molecules
Shows at least one CH3OH molecule, either all atoms together or with another shape in the key, completely surrouded with water
200
This is the molarity of 1 mol of KNO3 in 0.25 L of solution.
4 M OR 4 mol/L
200
This is the amount of KClO3 that could still be dissolved if you add 10g to 100g of water at 50°C.
What is 10g (+- 3)
200
These are the steps to creating a supersaturated solution.
What are first dissolving more solute at a high temperature, and then letting it cool until there is too much dissolved for the new temperature.
300
This is a particle diagram of one mole of CuCl2 that is fully dissolved, including the water molecules.
Shows at least 1 Cu and 2 Cls, all completely separated with water molecules inbetween.
300
This volume of a 2 M HCl solution contains 0.5 mol HCl
What is 0.25 L?
300
This is the mass needed to saturate 250 g of water at 90°C with NH4Cl
What is 175g? (+- 3)
300
This is the reason that increasing the concentration of a solution decreases its freezing temperature.
What is the solute particles preventing the liquid from getting close together until the temperature is even colder.
400
This is an experiment that will let you compare how strongly HCl and HNO3 are attracted to water.
What is comparing how well/how fast each solute dissolves in the same amount of water.
400
This is the moles of separate Cl ions in 0.75 L of a 1.5 M CaCl2 solution.
What is 2.26 mol?
400
This is the final temperature of a NH4Cl solution if we know 100g of water was saturated at 90°C and then cooled until 10g precipitated.
What is 70°C? (+- 3)
400
This is an experiment that would show whether a clear solution is saturated or unsaturated.
What is trying to dissolve more solute?
