inorganic chemistry Flashcards
inorganic chemistry
substances that do not contain carbon hydrogen bonds
7 inorganic substances in body
- water
- Acid
3.Base
4.Salts
5.Buffers - Carbon dioxide
- Oxygen
role of water in body
- thermoregulation by absorbing heat
- acts as lubricant/ padding
- part of chemical reactions necessary for life
- becomes mixture to transport substances throughout body
mixture
substances physically, but not chemically combined
suspension
materials separated unless stirred
colloid
small particles dispersed unevenly through out solution
solution
substances are uniformly distributed and chemically combined can be gas, liquid or solid,
solvent
that which dissolves the solute
solute
that which dissolves in the solvent
Blood is what kind of mixing medium
mixture, colloid and solution
acid
proton donor- releases H+
base
proton acceptor, bind and accept Hyrdogen ions OH-
pH scale
0-14
measure of H+
physiologic pH (pH of blood)
7.4
water pH
7–neutral
equal amount of H+ and Oh-
acidic pH
less than 7
contains more H+
basic pH
more than 7, contains less H+
role of Oxygen
air we breathe
required in final stage of reactions of breakdown of food for energy
role of Oxygen
air we breathe
required in final stage of reactions of breakdown of food for energy
role of carbon dioxide
metabolic waste
can be toxic if not exhaled–combines with water in plasma and can change pH
salt
cation other than hydrogen and anion other than oh–formed by interaction of acid and base
buffer
resists change for pH by binding to acid or base
