What is the difference between a titrant and Titrand?
A reagent, called the titrant or titrator is prepared as a standard solution. A known concentration and volume of titrant reacts with a solution of analyte or titrand to determine concentration. The volume of titrant reacted is called titration volume.
Titration is the slow addition of one solution of a known concentration (called a titrant) to a known volume of another solution of unknown concentration until the reaction reaches neutralization, which is often indicated by a color change.
- The equivalence point, or stoichiometric point, of a chemical reaction is the point at which chemically equivalent quantities of bases and acids have been mixed. The endpoint (related to, but not the same as the equivalence point) refers to the point at which the indicator changes colour in a colourimetric titration.
- The equivalence point is the point in a titration where the amount of titrant added is enough to completely neutralize the analyte solution. The moles of titrant (standard solution) equal the moles of the solution with unknown concentration. The equivalence point is not the same as the endpoint of a titration.
- An analyte, component (in clinical chemistry), or chemical species is a substance or chemical constituent that is of interest in an analytical procedure.
The titrant is usually the solution of known concentration that is delivered by a burette into a known quantity of the solution of unknown concentration. The volume of titrant used to reach the end point is termed the titre.
- Chemistry 104: Standardization of Acid and Base Solutions. Standardization is the process of determining the exact concentration (molarity) of a solution. Titration is one type of analytical procedure often used in standardization.
- In analytical chemistry, a standard solution is a solution containing an accurately known concentration of an element or a substance, A known weight of solute is dissolved to make a specific volume. Standard solutions are used to determine the concentrations of other substances, such as solutions in titration.
- The concentration of a basic solution can be determined by titrating it with a volume of a standard acid solution (of known concentration) required to neutralize it. The purpose of the titration is the detection of the equivalence point, the point at which chemically equivalent amounts of the reactants have been mixed.
The equivalence point is when the reactants are done reacting. The solution of unknown concentration is otherwise known as the analyte. During titration the titrant is added to the analyte in order to achieve the equivalence point and determine the concentration of the analyte.
- NaOH, or sodium hydroxide, is a very strong base, like everyone else is saying. So if the NaOH were to neutralize with an acid like, say, hydrochloric acid (HCl), the resulting NaCl would be a salt. And since the reaction was between a strong acid and a strong base, the resulting salt is a neutral salt.
- Standards are used in analytical chemistry. Here, a primary standard is typically a reagent which can be weighed easily, and which is so pure that its weight is truly representative of the number of moles of substance contained. Features of a primary standard include: High purity.
- Real Life Significance. Titration is used in laboratory medicine to determine unknown concentrations of chemicals of interest in blood and urine, for example. Pharmacists use titration in the development of new pharmaceuticals. Titration may also be used to determine the amount of a certain chemicals in food.
