Unit 7 Exam Review
What’s the difference?
DISSOCIATION & SOLVATION
SOLVATION ONLY
How much KCl can you dissolve at 40°C in 300 g H2O?
40 g × 3 = 120 g KCl
What type of solution?
STRONG ACID
Which indicator would you use to titrate a weak acid with a strong base?
Which is the solute?
ALCOHOL ACETONE
Which graph represents the relationship between vapor pressure and the amount of dissolved solute
particles?
Which graph represents the relationship between freezing point and the amount of dissolved solute
particles?
Which graph represents the relationship between boiling point and
the amount of dissolved solute particles?
Which graph represents the relationship between boiling point and
vapor pressure?
Which has the higher pH?

Which is the most common particle found in distilled water?
40 mL and 5.0 M how would you find g?
molM =
V
mol = M V→ ×
change mol to g (use MM)
1.9 L of 0.28 M diluted to 0.16 M.How would you find volume of
water added?
1 1 2 2M V = M V
2 1 2V ‐ V = vol H O added

What can you do to make the salt dissolve more quickly?
1) ↑ temp2) Break into
smaller pieces (↑ surface area)
3) Stir
What causes soda to go flat?
↑ temp or ↓ pressure
What property of oil causes this type of mixture?
Oil is nonpolar, and water is polar
The products are KNO3 and H2O. What type of reaction formed
these products?
NEUTRALIZATION RXN (DOUBLE‐REPLACEMENT)
The products are KNO3 and H2O. What were the reactants?
HNO3 + KOH KNO3 + H2O
How do you know something is a strong base based on its formula?
‐OH ion with an alkali or alkaline earth metal cation
How do you know something is an acid based on its formula?
H in front of formula
AgCl is a salt. Explain why it would stays solid in water.
Salt cannot by dissociated nor solvated by polar water molecules
