the acid dissociation constant (ka) is used to differentiate between strong and weak acids. the acid dissociates more as the ka increases. strong acids must therefore dissociate more in water. a weak acid, on the other hand, is less likely to ionise and release a hydrogen ion, leading to...
Weak Acid pH Calculator This is a calculator to find values of a weak acid dissociation reaction. All concentrations are measured in M (mol/liter). Values are found using the equilibrium constant formula, where the product of the concentration of products to the power of their coefficients is ...

Mathematically, pH is just the negative of the logarithm to the base 10 of the concentration of H+(or H3O+) ions: pH = –log10[H+]. As long as you have a calculator and are careful with your powers of 10, these calculations are straightforward. ...
Self Ionization of Water H2O H+ + OH- A reaction in water that produces ions. In pure water, the concentration of water molecules, [H2O] is constant at constant temperature. Calculating Molarity of [H+] or [OH-] [H+] [OH-]= Kw Kw is the ion product for water If [H+] inc...
An aliquot of 0.1 g of feces was saponified with 0.3 N KOH at 70 C for 1 h followed by extraction with petroleum ether to determine fecal neutral sterols by gas-liquid chromatography (Hewlett Packard HP6890 GC system using Ultra2 5% Phenyl column and flame ionization detector). Statistical ...
(ESI probe at 0.25 kV) with negative ionization (ionization temperature, 450 °C; cone voltage, 50 volts). Glucose and organic acids were quantified on a Dionex Ultimate 3,000 HPLC system equipped with a UV and a RI (Shodex RI-101) detector using an Aminex HPX-87H column (...
Q2.What is the self-ionization of water? Answer:Pure water is considered to have some ions and thus, it possesses very low conductivity. The ions in the pure water are in equilibrium as: H2O (l) ⇔ H+(aq) + OH–(aq) The H+ions are smaller and have high mobility and thus, they...
