Neutralization Reactions and Titrations
Neutralization:
A neutralization reaction between an acid and a base in aqueous solution produces an ionic compound (generically referred to as a salt) and water. It can be described as a double exchange reaction in which the two compounds exchange cations. The pH of the product approaches 7. This is because the H⁺ and OH⁻ ions are being converted into water molecules. As their concentrations decrease, the pH will move closer to 7.
Titrations:
A titration is a procedure in which a neutralization reaction is monitored with an indicator (such as phenolphthalein) allowing you to calculate the unknown concentration of an acid or base
If the solution is acidic, a standard base solution is added until it is neutralized and vice versa.
The end point is indicated by a color change and is when the number of H⁺ ions is equivalent to the number of OH⁻ ions. Calculations are based off of the following formula
(Volume of acid)(Molarity of H⁺) = (volume of base)(Molarity of OH⁻)
