base meaning chemistry
Sodium hydroxide (NaOH) and calcium hydroxide [Ca(OH)2] are examples of bases used in the laboratory.
In fact, some strong acids can act as bases. They tend to be slippery to the touch (e.g., soap), can taste bitter, react with acids to form salts, and catalyze certain reactions. OH- ions are called hydroxide ions. Examples of Rouelle's bases included alkalis, metals, oils, or absorbent earth. "Basic changes in public opinion often occur because of shifts in concerns and priorities"a basic course in Russian; a set of basic woodworking tools.B(eginner's) A(ll-purpose) S(ymbolic) I(nstruction) C(ode) What is the definition of a base in chemistry? Examples of bases include alkali metal hydroxides, alkaline earth metal hydroxides, and soap.The word "base" came into use in 1717 by French chemist Louis Lémery. Paracelsus proposed natural salts grew as a result of a universal acid mixing with a matrix.While Lémery may have used the word "base" first, its modern usage is generally attributed to French chemist Guillaume-François Rouelle. So, it made sense to early chemists that the material that neutralized the acid somehow destroyed its "spirit" and allowed it to take solid form.Bases may be categorized according to their degree of dissociation in water and reactivity.An acid and a base react with each other in a neutralization reaction. Substances containing a base are called basic substances. Base Definition in Chemistry.

Therefore, when dissolved in a solution, a part of the weak base dissociates into hydroxide anions and the relevant conjugate acid, and another part remains undissociated inside the solution. In neutralization, an aqueous acid and aqueous base produce an aqueous solution of salt and water. Lémery used the word as a synonym for Paracelsus' alchemical concept of a "matrix" in alchemy.

They tend to be slippery to the touch (e.g., soap), can taste bitter, react with acids to form salts, and catalyze certain reactions. Rouelle defined a neutral salt as the product of the union of an acid with another substance that acted as a "base" for the salt.
This definition includes not only Brønsted-Lowry proton transfer reactions, but also includes reactions in which no proton transfer is involved. What is a Base?
