    • n alkalimeter An instrument used for ascertaining the strength of alkalis, or the quantity of alkali in caustic potash and soda. This is done by determining what quantity of dilute sulphuric acid of a known strength can be neutralized by a given weight of the alkali or of caustic potash or soda. Sometimes spelled alcalimeter.
    • n alkalimeter An instrument for the quantitative analysis of carbonated alkali. It consists essentially of a thin glass vessel which can be weighed on a delicate balance and is so constructed that a known weight of sodium carbonate or acid carbonate contained in one division is kept from acid contained in another division during the first weighing. The acid is then run on the carbonate, causing an evolution of carbon-dioxid gas, which, in passing out of the apparatus, bubbles through concentrated sulphuric acid or passes over calcium chlorid and is thus deprived of moisture. The apparatus is weighed a second time, the loss in weight representing the carbon dioxid evolved and thus indicating the quality of the carbonate. As a precaution, dry air is drawn through the apparatus to displace any residual gas. Special forms have been devised by Bunsen, Fresenius, Schroetter, Mohr, and others.

For example, experimental measurements of the change in work function as a function of alkalimetal coverage can be quite different to the “expected” form of Fig. 5.16 and the density of states induced by alkali-metal adsorbates may not correspond to that expected from the model of Gurney.

This is indeed the case of magnetic traps: since the magnetic moments of the alkalimetals are very similar, the only difference in the trapping strengths is due to their different masses, with the angular trapping frequencies scaling as ωf /ωb ≃ (mb /mf )1/2 .
