Neutralization, the chemical reaction combining an acid with a base to produce a neutral solution, produces a salt and water.

Neutralization is a double displacement chemical reaction where an acid reacts with a base to form a salt and water. The reaction only products neutral compounds and is reversible in nature.

Based on Arrhenius' acid and base theory, an acid  when dissolved in water produces positive hydrogen () ion and negative non-metal ions. A base when dissolved in water produces positive metal ions and negative hydroxide () ions. When an acid reacts with a base, the hydrogen ions react with the hydroxide ions to form water.

→

The metal and non-metal ions combine to form a neutral ionic compound, the salt.

Eg: Combination of Sodium Hydroxide () and hydrochloric acid () forms Water () and Common salt ()

answer: semi-infinite solid initially at a uniform temperature of 400 ◦c is cooled at its surface by convection. the cooling fluid at a constant temperature of 200 ◦c has a convective coefficient (ha) of 250 w/m2.k. the physical properties of the solid: k = 20 w/m.k and α = 4 * 10-5  m2/s. using δx = 0.04 m and δt = 10 s. write the finite difference equations describing the transient heat transfer of the first five δx and the temperature profile after 30 s.
