Gemeenschappelijke Ioneffect
Compared with pure water, the solubility of an ionic compound is less in aqueous solutions containing a common ion (one also produced by dissolution…
Buffers
A solution containing appreciable amounts of a weak conjugate acid-base pair is called a buffer solution, or a buffer. Buffer solutions resist a…
Henderson-Hasselbalch Vergelijking
The ionization-constant expression for a solution of a weak acid can be written as: Rearranging to solve for [H3O+] yields: Taking the negative…
Berekenen van Veranderingen in pH in een Bufferoplossing
A buffer can prevent a sudden drop or increase in the pH of a solution after the addition of a strong acid or base up to its buffering capacity;…
Effectiviteit van Buffers
Buffer solutions do not have an unlimited capacity to keep the pH relatively constant . Instead, the ability of a buffer solution to resist changes…
Zuur-base Titratiecurven
A titration curve is a plot of some solution property versus the amount of added titrant. For acid-base titrations, solution pH is a useful property…
Berekenen van Titraties: Sterk Zuur - Sterke Base
Calculating pH for Titration Solutions: Strong Acid/Strong Base A titration is carried out for 25.00 mL of 0.100 M HCl (strong acid) with 0.100 M of…
Berekenen van Titraties: Zwak Zuur - Zwakke Base
Calculating pH for Titration Solutions: Weak Acid/Strong Base For the titration of 25.00 mL of 0.100 M CH3CO2H with 0.100 M NaOH, the reaction can be…
Indicatoren
Certain organic substances change color in dilute solution when the hydronium ion concentration reaches a particular value. For example,…
Titratie van een Polyprotisch Zuur
A polyprotic acid contains more than one ionizable hydrogen and undergoes a stepwise ionization process.  If the acid dissociation constants of…
Oplosbaarheidsproduct
Solubility equilibria are established when the dissolution and precipitation of a solute species occur at equal rates. These equilibria underlie many…
Factoren die de Oplosbaarheid Beïnvloeden
Compared with pure water, the solubility of an ionic compound is less in aqueous solutions containing a common ion (one also produced by dissolution…
Vorming van Complexe Ionen
A type of Lewis acid-base chemistry involves the formation of a complex ion (or a coordination complex) comprising a central atom, typically a…
Neerslag van Ionen
Predicting Precipitation The equation that describes the equilibrium between solid calcium carbonate and its solvated ions is: It is important to…
Kwalitatieve Analyse
For solutions containing mixtures of different cations, the identity of each cation can be determined by qualitative analysis. This technique…
Synthesis, Cellular Delivery and <em>In vivo</em> Application of Dendrimer-based pH Sensors
The development of fluorescent indicators represented a revolution for life sciences. Genetically encoded and synthetic fluorophores with sensing…
Synthesis of High Purity Nonsymmetric Dialkylphosphinic Acid Extractants
We present the synthesis of (2,3-dimethylbutyl)(2,4,4'-trimethylpentyl)phosphinic acid as an example to demonstrate a method for the synthesis of…
Sulfate Separation by Selective Crystallization with a Bis-iminoguanidinium Ligand
A simple and effective method for selective sulfate separation from aqueous solutions by crystallization with a bis-guanidinium ligand,…
