Quiz #5 Flashcards
What happens during the ionization of water
Hydrogen and OH- split
You get acids and bases through
Ionization of water
Acids are solutions that
Are full of hydrogen ions
Bases are solutions that
Are full of hydroxide/hydroxyl ions
Salts are
Ions that are not hydrogen of hydroxide
They bond easily because are unstable
Buffers are also known as
Alkaline a
Buffers/alkalines
Give you an alkaline test for hydroxide
They are bases
A buffer/alkaline will protect from acid rain
What is acid rain made of
H +
Making not an acid
You balance an acid with a
Base
If you take hydrogen from acids and add hydroxide from bases you get ______ which has a ______ pH of _____
Water
Neutral
7
The lower you get on the pH scale the _____ acidic the thing getsv
More
Polarity of a water molecule
Opposite charges on opposite ends of a molecule
Hydrogen bonding involves
Hydrogen being bonded to another atom or molecule or compound
Hydrogen bonding happens due to
The small size of hydrogen
This forms a relatively weak bond
True or false: water at tracks other ions
True
Temperature and stabilizing affects
Water absorbs much heat or cold before changing state
Water absorbing much heat or cold before changing state is called its
High heat capacity
Cohesion is when
Water sticks to water
When water sticks to water it gets the ability to
Stretch
Adhesion
Sticking to other matter
During adhesion, when things stick to other matter it creates
Cappilary action
Mixtures
Combine but not chemically
Solutions are what kind of mixture
Homogeneous
Solvent
Substance that dissolves another
