“Tribasic” means one mole of the acid will dissociate in water to produce 3 moles of hydrogen ions.
“weak acid” means that the acid molecules dissociate partially when dissolved in water to produce a low concentration of hydrogen ions.
Add a few drops of acidified potassium manganate(VII) solution to a solution containing an unknown agent.
If a reducing agent is present in the solution, the KMnO4 solution will turn from purple to colorless.
In the presence of a reducing agent, a redox reaction occurs, turning the Mn7+ ion in KMnO4 (which is purple) to Mn2+ ion (which is colorless or slightly pinkish).
Add a few drops of aqueous potassium iodide to a solution containing an unknown agent.
If an oxidizing agent is present in the solution, aqueous potassium iodide will turn from colorless to brown.
In the presence of an oxidizing agent, a redox reaction occurs, turning the iodide ion in KI (which is colorless) to iodine, I2 (which is brown).
Enthalpy change is the amount of energy involved in a reaction.
Electrolysis is the conduction of electricity by an ionic compound (an electrolyte), when molten or dissolved in water, leading to the decomposition of the electrolyte.
An atom that does not have a full valence shell will have a tendency to gain or lose valence electrons in order to achieve a stable electronic configuration.
Isotopes are atoms of the same element with the same number of protons but different number of neutrons.
Temperature, state of matter (gas/liquid/solid), relative molecular mass
Ammonium chloride, iodine crystals, dry ice, naphthalene.
