Duloxetine is also sometimes used to treat stress urinary incontinence (leakage of urine during physical activity such as coughing, sneezing, laughing, and exercise) in women. Talk to your doctor about using this medication to treat your condition.
Water's density maximum is a product of the same phenomenon. Close to the freezing point, the water molecules start to arrange locally into ice-like structures. This creates some openness in the liquid water, which tends to decrease its density.
The magnitude of the decrease of freezing point depends on the concentration of the dissolved substance and on the cryoscopic constant, which is a unique characteristic of each solvent. As an example, calculate the freezing point of the solution obtained by dissolving 15 g of sodium chloride (NaCl) in 100 g of water.
