Solutions

A solution that contains all of the solute it can hold at a given temperature is

• diluted.

• saturated.

• supersaturated.

• unsaturated.

The _____is the part that gets dissolved. 

• solute 
• solvent 
• solution 
• salute

When the solvent of the solution is water we call it _________. 

• a wet solution

• water mixture 
• hydrated

• aqueous 

What is the correct formula to solve for the Molarity of a solution that has .4 moles of HCl in 9.5 L of solution?

• M = 9.5 L / .4 mol
• M₁V₁=M₂V₂
• M = .4 mol / 9.5 L
• Convert .4 mol to grams then divide by 9.5

When ionic compounds dissolve, what happens?

• The atoms get smaller

• They break into their separate ions

• They stay together as a molecule

• They create new bonds

50 ml of a 1 M solution is diluted until the final volume is 80ml. How much water was added?

• 50 ml

• 1.3 ml

• 30 ml

• 130 ml

Which sweet tea would you expect to taste the sweetest?

• 1M
• 3M

If 1 mole of solute is dissolved in 2 liter of water, what is the molarity?

• 2M

• .5M

• 1M

• It can't be determined unless you know the solute

As we dilute a solution.....

• The volume increases and the molarity (M) increases

• The volume increases and the molarity (M) decreases

• The volume decreases and the molarity (M) increases

• The volume decreases and the molarity (M) decreases

How many mols of HCl are in 3 liters of 2.0M HCl solution?

• 2.0

• 1.5

• 6.0

• 0.66
