AND ANSWERS WITH COMPLETE SOLUTIONS VERIFIED
pH scale
measurement system used to indicate the concentration of hydrogen ions (H+) in
solution; ranges from 0 to 14
Hair and skin pH
4.5-5.5
pH scale measures
the concentration of hydrogen ions in a solution
pH is a logarithmic scale
every time you move it is a multiple of ten
Acid
A substance that increases the hydrogen ion concentration of a solution.
water ionizes
When covalent bonds of a water molecule break Spontaneously, it dissociates into H+
and OH- a process called ionization. H+(hydrogen ion) contributes to the acidity of a
solution, while OH-(hydroxide ion) contributes to the alkalinity (basic) of a solution.
ph
potential hydrogen; scale to indicate degree of acidity or alkalinity
Ion
An atom or group of atoms that has a positive or negative charge.
, ion with a negative charge
anion
ion with a positive charge
cation
Ionization
the process of adding or removing electrons from an atom or molecule, which gives the
atom or molecule a net charge
true or false - products that contain water can have a PH
true
Volitile organic compounds (VOC)
Hydrocarbons (carbons that contain hydrogen-carbon bonds, such as gasoline, lighter
fluid, etc.)
Ammonia
A small, very toxic molecule (NH3) produced by nitrogen fixation or as a metabolic
waste product of protein and nucleic acid metabolism.
water-in-oil emulsion
Abbreviated W/O emulsion; water droplets are emulsified in oil.
Suspension
A mixture in which particles can be seen and easily separated by settling or filtration
example of suspension
glitter in nail polish
pH definition
a measure of the hydrogen ion concentration of a solution
