The role of water in the association equilibrium is ignored as in all but the most concentrated solutions the activity of water is constant. K is defined here as an association constant, the reciprocal of an acid dissociation constant. Each activity term { } can be expressed as the product of a concentration [ ] and an activity coefficient γ ...
The activities a are related to the concentrations c by a=γc where γ is the activity coefficient. The equilibrium potential is given by the Nernst equation : E e = − Δ G n F = E o + R T n F ln ( a o e a r e ) {\displaystyle E_{e}=-{\frac {\Delta G}{nF}}=E^{o}+{\frac {RT}{nF}}\ln \left({\frac {a_{oe}}{a_{re}}}\right)}
A variety of standard sizes of primary cells. From left: 4.5V multicell battery, D, C, AA, AAA, AAAA, A23, 9V multicell battery, (top) LR44, (bottom) CR2032 A primary battery or primary cell is a battery (a galvanic cell) that is designed to be used once and discarded, and it is not rechargeable unlike a secondary cell (rechargeable battery).

A wire connects two different metals (e.g. zinc and copper). Each metal is in a separate solution; often the aqueous sulphate or nitrate forms of the metal, however more generally metal salts and water which conduct current. [4] A salt bridge or porous membrane connects the two solutions, keeping electric neutrality and the avoidance of charge ...
Ohio Sen. Sherrod Brown (D) said he’s “not dismissing” another Senate run after he was defeated in his run for reelection this year. Brown spoke with CNN’s Manu Raju on Sunday, where he ...
In electrochemistry, the Nernst equation is a chemical thermodynamical relationship that permits the calculation of the reduction potential of a reaction (half-cell or full cell reaction) from the standard electrode potential, absolute temperature, the number of electrons involved in the redox reaction, and activities (often approximated by concentrations) of the chemical species undergoing ...
A report by the Australian Competition and Consumer Commission said that while the integration of generative AI tools into search engines is still nascent, Big Tech's deep pockets and dominant ...
