Freezing point depression and boiling point elevation In chemistry , colligative properties are those properties of solutions that depend on the ratio of the number of solute particles to the number of solvent particles in a solution, and not on the nature of the chemical species present. [ 1 ]
The reason is that the test may be falsely normal (false negative) in many cases or abnormally elevated in people who have no cancer (false positive) in others. The main use of CA19-9 is therefore to see whether a pancreatic tumor is secreting it; if that is the case, then the levels should fall when the tumor is treated, and they may rise ...

For most ionic compounds dissolved in water, the van 't Hoff factor is equal to the number of discrete ions in a formula unit of the substance. This is true for ideal solutions only, as occasionally ion pairing occurs in solution. At a given instant a small percentage of the ions are paired and count as a single particle.
For the United States, with a standard maximum unbalanced superelevation of 75 mm (3 in), the formula is this: v m a x = E a + 3 0.00066 d {\displaystyle v_{max}={\sqrt {\frac {E_{a}+3}{0.00066d}}}} where E a {\displaystyle E_{a}} is the superelevation in inches, d {\displaystyle d} is the curvature of the track in degrees per 100 feet, and v m ...
