Vocabulary
This is the thing that gets dissolved into a solution. (For example, the lemonade powder when making lemonade.)
What is a solute?
This is the molarity of 0.5 moles of NaCl dissolved in 0.05 L of solution.
What is 10 M?
How much NH3 can dissolve in 100mL of water at 10 degrees?
70 g
If the volume of solution stays the same, but more solute is added, this is what will happen to the molarity of the the solution.
What is increase?
The only metal that is liquid at room temperature
Hg = Mercury
This is the number of moles per liter in a solution.
What is molarity?
This is the number of moles present in 0.6 L of a 1.55 M Na Cl solution.
What is 0.93 moles?
What solute's solubility is least effected by temperature changes?
NaCl
If the number of moles stays the same, but the volume of the solution increases, this is what will happen to the molarity.
What is decrease?
What is the only letter NOT on the periodic table?
J
A solution that has reached the point where no more solution will dissolve is called this.
a 100ml, 3 M solution of acid is diluted and is now 200ml. What is the new molarity?
1.5 M
This is the substance on the graph with the highest solubility at a temperature of 10 degrees.
What is KI?
For most substances, if the temperature of the solvent increases, the solubility will do this.
What is increase.
What is the most abundant element on earth?
Hydrogen
The number of grams of solute that can dissolve in 100 g (or 100 ml of water) is called this.
What is solubility?
If you dilute 175 mL of a 1.6 M solution of LiCl to 1.0 L, determine the new concentration of the solution.
0.28 M
This is chemical is rare because its solubility decreases as the temperature increases.
What is Ce2(SO4)2 or NH3?
Draw a graph showing solubility of a gas over temperature.
Negative slope!
What is the Molarity of human blood?
0.28 M
This fancy vocabulary term describes a solid that is deposited from a solution.
What is a precipitate?
This is the number of grams of Ca(OH)2 needed to produce 0.5 L of 1.66 M Ca(OH)2 solution.
What is 61.5 g?
At a temperature of 50 degrees, this is how many grams of NH4Cl would be expected to dissolve.
What is 50 g?
If an unsaturated solution is cooled to a temperature at which the solubility is now above the solubility curve, this is what an observer would see.
A precipitate/solid would be formed from the excess solute.
This is the % of a watermelon that is actually composed of water.
About 92 %
