Properties of Water Flashcards
What is the attraction between a hydrogen atom on one water molecule and the oxygen atom on another is known as?
hydrogen bond
Which bond gives water its special properties?
hydrogen bonds
What are water’s special properties?
cohesion (attraction between molecules of the same substance), adhesion (attraction between molecules of different substances), and high heat capacity
How does water’s polarity influence its properties as a solvent?
It is able to dissolve both ionic compounds and other polar molecules
What is a mixture?
A material composed of two or more elements or compounds that are physically mixed together but not combined chemically
What is a solution
A type of mixture that is evenly dispersed
What is a solute?
a substance that is dissolved
What is a solvent?
A substance in which the solute dissolves
What is a suspension?
A type of mixture of water and a no dissolved material
What is the pH scale?
A measurement system that indicates the concentration of H+ ions in a solution
From 0-14 which number(s) on the pH scale are basic?
8-14 (the higher the more basic)
From 0-14 which number(s) on the pH scale are neutral?
7
From 0-14 which number(s) on the pH scale are acidic?
0-7 (the lower the more acidic)
What is an acid?
Any compound that forms H+ ions in solution
What is a base?
A compound that produces hydroxide (OH-) in solution
