Question
The heat of this process is the leftover background signal once binding is finished in isothermal titration calorimetry. Phase-separated helium isotopes cool a cryogenic refrigerator named for this process. At the infinite limit of this process, a chemical’s activity coefficient reaches a limiting value, its vapor pressure obeys Henry’s law, and its mole fraction approaches (*) zero. An assay standard curve is prepared by performing this process serially in log-fold decrements, pipetting a stock from tube-to-tube. This process names the equation “C1 V1 equals C2 V2.” Colligative properties vanish as this general process is done, since it lowers molality. For 10 points, name this decrease in a solution’s concentration. ■END■
ANSWER: dilution [or diluting; or making it more dilute; prompt on increasing volume or decreasing concentration or decreasing molarity]
