- Chemistry : The science of matter, or of the electrical or electrostatical interactions of matter.
- Physical chemistry : The application of physics to macroscopic, microscopic, atomic, subatomic, and particulate phenomena in chemical systems within the field of chemistry traditionally using the principles, practices and concepts of thermodynamics, quantum chemistry, statistical mechanics and kinetics.
- Charge : Please do not use this term in your topic list, because there is no single article for it. Please substitute a more precise term. See Charge (disambiguation) for a list of available, more precise, topics. Please add a new usage if needed.
- Ion : An atom or molecule where the total number of electrons is not equal to the total number of protons, giving it a net positive or negative electrical charge.
- Acid : A chemical that accepts electron pairs, but sometimes defined as proton (H+) or hydronium (H3O)+ ion donors.
- : A molecule that can accept protons.
- Water : A chemical compound with one oxygen and two hydrogen atoms (H20). It is often in a liquid form and makes up the bulk of the oceans, lakes, rivers and living organisms.
- : A piece of filter paper loaded with litmus that can act as a pH indicator; is used to test for the acidity of an aqueous solution; figurative basis for litmus test in politics.
- : An electronic instrument used to measure the acidity or alkalinity of a liquid in pH units.
- Affinity chromatography : Method to filter a specific molecule out of a solution.
- Atmosphere : The layers of gas surrounding stars and planets.
- Blood : The body fluid that circulates in the vascular system (i.e., blood vessels). Whole blood includes plasma and blood cells.
- Chemical equilibrium : The stage of a chemical reaction in which the forward and backward reactions level out.
- Chemotaxis : Add brief definition or description
- Environmental chemistry : The scientific study of the chemical and biochemical phenomena that occurs in natural places.
- Enzyme : A protein that catalyzes (i.e. accelerate) chemical reactions.
- Homeostasis (biology) : The coordinated physiological reactions which maintain most of the steady states in an organism.
- Homeostasis (a redirect)
- Ion-selective electrodes : A transducer (sensor) which converts the activity of a specific ion dissolved in a solution into an electrical potential which can be measured by a voltmeter or pH meter.
- Lactic fermentation : A form of fermentation that occurs in animal cells in the absence of oxygen.
- Ion channel : Gated, ion-selective glycoproteins that traverse membranes. The stimulus for channel gating can be a membrane potential, drug, transmitter, cytoplasmic messenger, or a mechanical deformation.
- Ion pump : General class of integral membrane proteins that transport ions across a membrane against an electrochemical gradient.
- Logarithm : Inverse of exponentiation, as subtraction is the inverse of addition and division is the inverse of multiplication.
