Definitions Flashcards
half life
is a time taken for the concentration of a given reactant to reach 50 % of its initial value
rate constant
it is the proportionality constant in a equation that expresses the relationship between the rate of a chemical reaction and the concentration of the reacting substance
order of reaction
the power by which concentrations are raised in rate equation
rate equation
the extent to which concentration determines the rate of a reaction is expressed as the rate equation
titration
it is volumetric analysis to find out the concentration of unknown solution with the help of know solution
equivalence point
when equal moles of acid is balanced by the same amount of alkali according to equation
indicators
is used to determine the equvialnce point by noticing the exact colour change
end point of titration
a point at which colour change
ligand
anion or molecule that has lone pair that donate its lone pair to the transition metal ion and form a dative covalent bond
complex ion
transition metal ion surrounded by ligand
formation
when one mole of compound from from its element understandrard condition element should be in their standard state
neutraliation
when 1 mole of water is formed from acid and base under standard condition
combustion
when 1 mole of substance burns in the presence of excess oxygen to produce carbon dioxide and water
solution
when one mole of solute dissolve in water and form infinte dilution understandard condition
standard hydrogen electrode
used as a refrence cell beacuse its value is 0.oov under standard condition
