What is K (Equilibrium Constant)? Geochemistry quick tips! In principle, any chemical equilibrium reaction can be described by the mass – action law. Where K = Thermodynamic equilibrium or dissolution constant K is truly defined based on the type of reaction in hand. For example: Dissolution / Precipitation reaction: K= Ks = Solubility product constant. [...]

Alkalinity (As of CaCO3 to As of HCO3-): Practical guide on unit conversion This article is for all young geochemist starting their work in consulting world! I went through the pain of discovering the facts that are not really taught in schools or in books. You can only learn them by playing with actual laboratory [...]
Geochemisrty quick tips: Cation Anion Balance or Charge Balance Error (C.B.E)!
Geochemistry quick tips: Cation Anion Balance or Charge Balance Error (C.B.E)! Are you lost during a geochemical investigation? Well, sometimes I do get lost. Sometimes I feel like I need more water quality parameters to answer some of the geochemical questions. I never thought about doing just a simple “cation – anion” balance before until [...]

Various concentration units used in ground water geochemistry
Various concentration units used in ground water geochemistry: – Molality: moles of solute per kilogram of solvent – Molarity: moles of solute per liter of solution Molarity = Molality for dilute solutions. Not valid for brines. – ppm: parts per million – ppb: parts per billion – Conc. in ppm = Conc. in mmol/kg x [...]
