hydrogenation : When hydrogen is added to a carbon-carbon multiple bond.
•
hydronium ion : The H+ ion, made famous by acids.
•
hydroxide ion : The OH- ion, made famous by bases.
•
ideal gas law : PV=nRT
•
ideal gas : A gas in which the particles are infinitely small, have a kinetic
energy directly proportional to the temperature, travel in random straight lines,
and don't attract or repel each other. Needless to say, there's no such thing
as an ideal gas in the real world. However, we use ideal gases anyway
because they make the math work out well for equations that describe how
gases behave.
•
ideal solution : A solution in which the vapor pressure is directly proportional
to the mole fraction of solvent present
•
immiscible : When two substances don't dissolve in each other. Think of oil
and water. They're immiscible. Organic compounds and water are frequently
immiscible.
•
indicator : A compound that turns different colors at different pH values. We
generally like to have the color change at a pH of around seven because that's
where the equivalence point of a titration is.
•
inhibitor : A substance that slows down a chemical reaction.
•
inorganic compound : Any compound that doesn't contain carbon (except for
carbon dioxide, carbon monoxide, and carbonates).
•
insoluble : When something doesn't dissolve.
•
intermediate : A molecule which exists for a short time in a chemical reaction
before turning into the product.
•
intermolecular force : A force that exists between two different molecules.
Examples are hydrogen bonding (which is strong), dipole-dipole forces (which
are kind of weak), and London dispersion forces (a.k.a. Van der Waal forces),
which are very weak.
