Base (chemistry) increase the hydronium (HO) concentration in water, whereas bases reduce this concentration. A reaction between an acid and base is called neutralization. In a neutralization reaction, an aqueous solution of a base reacts with an aqueous solution of an acid to produce a solution of water and salt in which the salt separates into its component ions. If the aqueous solution is saturated with a given salt solute, any additional such salt precipitates out of the solution. The notion of a base as a concept in chemistry was first introduced by the French chemist Guillaume François Rouelle in 1754. He
Radiation chemistry solution at 2.7 forms a mixture of the colloid and the soluble Tc(IV) compounds. Gamma irradiation has been used in the synthesis of nanoparticles of gold on iron oxide (FeO). It has been shown that the irradiation of aqueous solutions of lead compounds leads to the formation of elemental lead, when an inorganic solid such as bentonite and sodium formate are present then the lead is removed from the aqueous solution. Another key area uses radiation chemistry to modify polymers. Using radiation, it is possible to convert monomers to polymers, to crosslink polymers, and to break polymer chains. Both man-made
