Acid Base & Solubility Equilibria (Digital Notes)
$300.00 Add to cartSolubility equilibrium is a type of dynamic equilibrium that exists when a chemical compound in the solid state is in chemical equilibrium with a solution of that compound. The solid may dissolve unchanged, with dissociation, or with chemical reaction with another constituent of the solution, such as acid or alkali. Each solubility equilibrium is characterized by a temperature-dependent solubility product which functions like an equilibrium constant. Solubility equilibria are important in pharmaceutical, environmental and many other scenarios.

Gibbs Free Energy (Digital Notes)
Read moreGibbs free energy, denoted G, combines enthalpy and entropy into a single value. The change in free energy, ΔG, is equal to the sum of the enthalpy plus the product of the temperature and entropy of the system. ΔG can predict the direction of the chemical reaction under two conditions: 1. constant temperature and 2. constant pressure.

Nitrogen Compounds (Digital Notes)
$150.00 Add to cartNitrogen compounds such as urea, amine and guanidine are used to denature proteins, hence their antimicrobial properties. One special form of nitrogen compounds for antimicrobial treatment is the so-called quats or quaternary ammonium salts. These molecules have a positive charge, attracting the negatively charged cell membrane of microorganisms.
