    en.wikipedia.org/wiki/List_of_unsolved_problems...

    This is a list of unsolved problems in chemistry. Problems in chemistry are considered unsolved when an expert in the field considers it unsolved or when several experts in the field disagree about a solution to a problem.

  3. Stoichiometry - Wikipedia

    en.wikipedia.org/wiki/Stoichiometry

    Gas stoichiometry is the quantitative relationship (ratio) between reactants and products in a chemical reaction with reactions that produce gases. Gas stoichiometry applies when the gases produced are assumed to be ideal, and the temperature, pressure, and volume of the gases are all known. The ideal gas law is used for these calculations.

  4. Job plot - Wikipedia

    en.wikipedia.org/wiki/Job_plot

    In solutions where two species are present (i.e. species A and species B), one species (A) may bind to the other species (B). In some cases, more than one A will bind with a single B. One way to determine the amount of A binding to B is by using a Job plot.

  5. Redfield ratio - Wikipedia

    en.wikipedia.org/wiki/Redfield_ratio

    Since then experimentation has proven that Iron is a limiting factor for primary production. Iron-rich solution was added to 64 km 2 area which led to an increase in phytoplankton primary production. [21] As a result an extended Redfield ratio was developed to include this as part of this balance.

  6. Law of mass action - Wikipedia

    en.wikipedia.org/wiki/Law_of_mass_action

    The generalisation of the law of mass action, in terms of affinity, to equilibria of arbitrary stoichiometry was a bold and correct conjecture. The hypothesis that reaction rate is proportional to reactant concentrations is, strictly speaking, only true for elementary reactions (reactions with a single mechanistic step), but the empirical rate ...

  8. Equivalence point - Wikipedia

    en.wikipedia.org/wiki/Equivalence_point

    A drop of indicator solution is added to the titration at the start; when the color changes the endpoint has been reached, this is an approximation of the equivalence point. Conductance The conductivity of a solution depends on the ions that are present in it. During many titrations, the conductivity changes significantly.

  9. Oxygen reduction reaction - Wikipedia

    en.wikipedia.org/wiki/Oxygen_reduction_reaction

    The oxygen reduction reaction is an essential reaction for aerobic organisms. Such organisms are powered by the heat of combustion of fuel (food) by O 2.Rather than combustion, organisms rely on elaborate sequences of electron-transfer reactions, often coupled to proton transfer.
