Description
Potassium chloride solution 0,01 mol/l – 0,01 N is a volumetric standard solution formulated for analytical and quantitative laboratory work. It is identified by CAS number 7447-40-7 and empirical formula KCl, with a defined concentration of 0,01 mol/l (0,01 N) for titration, calibration and related volumetric procedures. Physical characteristics include a molar mass of 74,56 g/mol, density of approximately 1 g/cm³ and a boiling point of 100 °C. The product is packed as 1 l, providing a practical volume for routine bench use where a potassium chloride volumetric standard is required. Stated normality supports reproducible analytical results and method consistency. This solution from manufacturer Carl ROTH serves laboratories that need clearly specified volumetric reagents with documented chemical identity. EG number 231-211-8 further aids substance recognition for laboratory documentation, inventory management and analytical quality systems.
This article belongs on pH buffers & conductivity standards, in Buffers & pH solutions.

What is this article?
Potassium chloride solution, 0.01 mol/l - 0.01 N volumetric solution, 1 l is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in pH buffers & conductivity standards, inside Buffers & pH solutions, in Lab chemicals.
A pH buffer for calibration has a stated pH at a stated temperature, often traceable. A conductivity standard has a stated conductivity. They are not general reagents and they should not be poured back into the bottle. The temperature of the measurement has to be the temperature on the label, or the meter has to compensate.
A buffer resists a change in pH when a little acid or base is added. It does that because a weak acid and its conjugate base are both present. A pH buffer used to calibrate a meter has a stated value at a stated temperature. A biological buffer such as Tris or HEPES is chosen because it holds the pH of a living system and does not poison it. Conductivity standards are the sister articles for a conductivity meter. The ions are on PubChem. Electrode calibration practice sits with EURAMET and BELAC.
