Estimation of total, permanent and temporary hardness of ...

Page 2 of 6 2. Temporary hardness Temporary hardness is due to the presence of bicarbonates of calcium and magnesium ions. It can be easily removed by boiling. When water is boiled, temporary hardness producing substances (bicarbonates) are precipitated as insoluble carbonates or hydroxides. This precipitate can be removed by filtration.

Wavenumbers and Frequencies - Michigan State University

The relation between wavelength and frequency for electromagnetic radiation is . λν =c. In the SI system of units the wavelength . λis measured in meters (m) and since wavelengths are usually very small one often uses the nano meter (nm) which is 10-9 m. The frequency . ν in the SI system is measured in reciprocal seconds . s−1
