Water portal Tritiated water is a radioactive form of water in which the usual protium atoms are replaced with tritium. In its pure form it may be called tritium oxide (T2O or H2O) or super-heavy water. Pure T2O is corrosive due to self-radiolysis. Diluted, tritiated water is mainly H2O plus some HTO ( HOH). It is also … See more Tritiated water can be used to measure the total volume of water in one's body. Tritiated water distributes itself into all body compartments relatively quickly. The concentration of tritiated water in urine is assumed to be … See more Tritiated water contains the radioactive hydrogen isotope tritium. As a low energy beta emitter with a half-life of about 12 years, it is not dangerous externally because its beta … See more Web6. Do introduce some moisture - Sometimes when you are in an over-titration situation and the vessel is already very dark you can introduce a little moisture to bring the vessel back to equilibrium. This sometimes works and immediately the vessel turns from a dark burnt-red color to a light-yellow. 7. Do have a spare detector electrode on hand. WebAmino acids with nonpolar substituents are said to be hydrophobic (water-hating). ... If we only add half as much base, only half of the positive ions would be titrated to zwitterions. In other words, the concentration of the H 3 N + CH 2 CO 2 H and H 3 N + CH 2 CO 2-ions would be the same. Or, using the symbolism in the Henderson-Hasselbach ... esther gaines
