Questions about Volumetric standard solutions (titration)

Molarity or normality?

Molarity (mol/l, M) counts moles of the substance per litre. Normality (N) counts reactive equivalents, such as the H⁺ or OH⁻ the solution can deliver in the titration. For monoprotic acids and for sodium hydroxide the two are the same, so 0.1 mol/l equals 0.1 N, as with the sodium hydroxide volumetric solution 0.1 M (0.1 N), 1 l. Sulphuric acid releases two protons, so 1 mol/l equals 2 N. This is why the sulphuric acid volumetric solution 5 mol/l (10 N), 1 l lists both units. Check which unit your method uses before you calculate.

Which concentration should I choose?

Match the concentration to the amount of analyte you expect and to your burette volume. If the titrant is too concentrated, you use only a few drops and small reading errors weigh heavily on the result. If it is too dilute, the burette runs empty before the end point. For most routine acid-base titrations, 0.1 mol/l is a good starting point, for example the hydrochloric acid volumetric solution 0.1 M, 1 l. For high contents, use a stronger solution such as the sodium hydroxide 2.0 M, 1 l. For traces, use a weaker one. Questions: sales@luminixhealth.com.

Ready-to-use or standardise yourself?

A ready-to-use volumetric solution comes at a stated concentration. You can use it straight from the bottle, which saves preparation time and reduces errors, for example the sodium hydroxide volumetric solution 0.1 M, 1 l. Many labs still check the titre regularly against a primary standard, as their quality system requires. If you prefer to make your own, ampoule concentrates give a defined amount to dilute to volume, such as the hydrochloric acid concentrate for 1 l of 0.1 M solution. You then need an accurate volumetric flask and you standardise the solution yourself. Flasks are in volumetric glassware.

How long does a volumetric solution keep?

Check the shelf life stated on the label or the product page, and note the opening date on the bottle. After opening, the titre can drift. Sodium hydroxide absorbs carbon dioxide from the air, so its concentration slowly falls, as with the sodium hydroxide volumetric solution 0.1 M. Close the bottle straight after use and do not pour unused solution back. Dilute acids, such as the sulphuric acid volumetric solution 0.025 mol/l, 1 l, are more stable but can still pick up contamination. Check the titre at fixed intervals.

Why Volumetric standard solutions (titration)?

A volumetric standard solution is a reagent of stated concentration for titration, such as a stated molarity of acid, base or silver nitrate. The factor or the exact titre is on the certificate. Using the nominal molarity when a factor is printed is a systematic error.

A reference material is the article against which another result is compared. Its value is stated, and the uncertainty of that value is part of the product. An ICP or ion standard is a solution of known concentration. A volumetric standard is for titration. A chromatography standard is the peak you match. The grade names, including pharmacopoeia and ASTM, say which impurities were limited. Identity is checked on PubChem. Names follow IUPAC. Medicinal grades follow the European Pharmacopoeia and USP.
