2.4 properties of water

Question 1

Cohesion and Adhesion

Answer 1

Cohesion is H bonding between H2O molecules.
Adhesion is H bonding between H2O and other molecules.

Question 2

Solvent

Answer 2

Solvents dissolve solutes creating a solution. Polarity makes water a good solvent.

Question 3

Specific heat

Answer 3

Question 4

heat of vaporization

Answer 4

The amount of energy it takes for 1 gram of water to evaporate.

Question 5

concentration

Answer 5

How much solute is in a solvent or solution.

Question 6

pH or pOH

Answer 6

pH measures [H3O+] on a logarithmic scale. pOH measures [OH-].

Question 7

Hydroxide and hydronium

Answer 7
