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
Chemistry: A Volatile History with a different solution to win the atomic race. Now finally, scientists’ dream of creating an element beyond the end of the periodic table was about to be realized. In California, scientists were trying to create a new element heavier than uranium using cyclotron machines. This involved using huge magnets to steer atoms round in circles faster and faster until they reached a tenth of the speed of light, whereupon they were smashed into a uranium target. Edwin McMillan and Philip H. Abelson blasted uranium with a beam of particles to create the first synthetic element, heavier than uranium –
