Let a weak acid be HA, which ionizes into its aqueous solution and produce H3O+ and A− ions. HA(aq)+H2O(l)⇌H3O+(aq)+A−(aq) The acid ionization constant is defined as ka=[H3O+]×[A−][HA] ⇒[H...
A 0.20 M solution of the weak acid HA has (H+) = 1.4 x 10-4 M. What is the acid ionization constant, Ka, for this acid? What is the ionization constant at 25oC for the weak acid (CH3)2 NH2+,the con...
The particles quickly swell and absorb water, urine, or other aqueous solutions. Polyacrylic acid is a polyelectrolyte which is soluble in aqueous media at neutral pH, due to the ionization of the pendent carboxyl side chains. Carbopols are polymers of acrylic acid that have been cross-linked ...
Ionization constant is a mathematical constant that's used in chemistry to measure the acidity or basicity of a solution. Most...

Tungsten is a non-ferrous metal and an important strategic metal. Tungsten ore was called “heavy stone” in ancient times. In 1781, the Swedish chemist Carl Wilhelm Scheele discovered scheelite and extracted a new element acid-tungstic acid. In 1783, it was discovered by the Spanish Depuria...
