Groundwater chemistry Charles R. Fitts, in Groundwater Science (Third Edition), 2024 10.5.2 Activity and effective concentration Equilibrium equations are written based on the assumption of an ideal solution, one where ions move and collide in a random way. In solutions with very low ion concen...
The unconstrained GAB–BET equation is capable of describing concentration-dependent dose–response curves that do not exhibit saturation. The GAB–BET equation for finite layers exhibits saturation but increases more slowly than the comparable Michaelis–Menten and Hill equations. The fitting results of...
The Freundlich equation states that, at a constant temperature, the amount of adsorbate bound per unit weight of adsorbent, Qe (adsorption efficiency of the adsorbent) is a logarithmic function of the residual concentration in the fluid phase at equilibrium, Ce. At low-solute concentrations, the ...
Learn about Le Chatelier's Principle and equilibrium. Explore examples of Le Chatelier's Principle in terms of concentration, pressure, and...
are typically water and a salt. It is useful to know how to solve neutralization equations because they are often involved in chemistry experiments and they can help you to better understand the differences between acids and bases. Tables of strong acids and bases are often provided for ...
, concentration of both the species are same or in other words, acid will be half dissociated. Similarly, for a weak base B: \(\begin{array}{l}B~ +~ H_2O~ ⇋ ~ OH^− ~+~ HB^+\end{array} \) Base dissociation constant, Kb, of the base can be given as, ...
Dilution is the process of decreasing the concentration of solute in a solution by changing the amount of solvent. The dilute solution definition requires an understanding of basic mixture chemistry. A solution is a type of mixture where one substance, the solute, is dissolved in another substance...
The term "pH" is a measure ofhydrogenionconcentration, a quantitative measure of theacidityoralkalinityof asolution. In chemistry, the pH scale usually ranges from 0 to 14.Aqueous solutionsat 25°C with a pH of less than 7 areacidic, while those with a pH greater than 7 are basic oralk...
A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge is the same for both the reactants and the products. In other words, the mass and the charge are balanced on both sides of the reaction. Also ...
