Wilhelm Ostwald ’s dilution law is a relationship proposed in 1888 [ 1 ] between the dissociation constant K d and the degree of dissociation α of a weak electrolyte . The law takes the form [ 2 ]
Where the square brackets denote concentration, and c 0 is the total concentration of electrolyte.
Using α = Λ c / Λ 0 {\... | https://en.wikipedia.org/wiki/Law_of_dilution |
In chemistry , the law of mass action is the proposition that the rate of a chemical reaction is directly proportional to the product of the activities or concentrations of the reactants . [ 1 ] It explains and predicts behaviors of solutions in dynamic equilibrium . Specifically, it implies that for a chemical reactio... | https://en.wikipedia.org/wiki/Law_of_mass_action |
In chemistry, the law of multiple proportions states that in compounds which contain two particular chemical elements, the amount of Element A per measure of Element B will differ across these compounds by ratios of small whole numbers. For instance, the ratio of the hydrogen content in methane (CH 4 ) and ethane (C 2 ... | https://en.wikipedia.org/wiki/Law_of_multiple_proportions |
The law of rational indices is an empirical law in the field of crystallography concerning crystal structure . The law states that "when referred to three intersecting axes all faces occurring on a crystal can be described by numerical indices which are integers, and that these integers are usually small numbers." [ 2 ... | https://en.wikipedia.org/wiki/Law_of_rational_indices |
The law of reciprocal proportions , also called law of equivalent proportions or law of permanent ratios , is one of the basic laws of stoichiometry .
It relates the proportions in which elements combine across a number of different elements. It was first formulated by Jeremias Richter in 1791. [ 1 ] A simple statemen... | https://en.wikipedia.org/wiki/Law_of_reciprocal_proportions |
The law of specific nerve energies , first proposed by Johannes Peter Müller in 1835, is that the nature of perception is defined by the pathway over which the sensory information is carried. Hence, the origin of the sensation is not important. Therefore, the difference in perception of seeing, hearing, and touch is n... | https://en.wikipedia.org/wiki/Law_of_specific_nerve_energies |
The law of squares is a theorem concerning transmission lines . It states that the current injected into the line by a step in voltage reaches a maximum at a time proportional to the square of the distance down the line. The theorem is due to William Thomson , the future Lord Kelvin. The law had some importance in c... | https://en.wikipedia.org/wiki/Law_of_squares |
The law of symmetry is a law in the field of crystallography concerning crystal structure . The law states that all crystals of the same substance possess the same elements of symmetry. The law is also named the law of constancy of symmetry , Haüy's law or the third law of crystallography .
The way in which the law of... | https://en.wikipedia.org/wiki/Law_of_symmetry_(crystallography) |
The law of the handicap of a head start (original Dutch : Wet van de remmende voorsprong ) , also known as the first-mover disadvantage or dialectics of lead , is a theory in economic history and technological development that proposes that an initial head start in a particular domain may paradoxically become a handica... | https://en.wikipedia.org/wiki/Law_of_the_handicap_of_a_head_start |
