The presence of a nonvolatile solute in an aqueous solution lowers the vapor pressure of the solution, raising its boiling point and lowering its freezing point compared to the pure solvent. This occurs due to the solute molecules occupying space at the surface of the solution, reducing the number of solvent molecules escaping into the vapor phase. As a result, a higher temperature is needed to reach the same vapor pressure as the pure solvent for boiling, and a lower temperature is needed for the solution to freeze.

What are the relationships between electrolyte specific gravity freezing point and state of charge?
The specific gravity of an electrolyte solution can provide an indication of its state of charge, with higher specific gravity typically indicating a higher state of charge. The freezing point of the electrolyte solution decreases as the state of charge increases, due to the higher concentration of sulfuric acid in the solution. By measuring the specific gravity and freezing point of an electrolyte solution, you can gain insights into its state of charge and overall health of the battery.
Explain why a solution has a lower boiling point than the pure solvent?
When a solute is added to a solvent, the vapor pressure of the solution decreases compared to the pure solvent. This means the solution needs less energy to overcome atmospheric pressure and boil. As a result, the boiling point of the solution is lower than that of the pure solvent.
When some aci is added to a solution of an alkali will the pH value of the solution increase or decrease explain?
When an acid is added to a solution of an alkali, the pH of the solution will decrease. This is because the acid will increase the concentration of hydrogen ions, leading to a more acidic solution.

Explain why molality is used for boiling point elevation and feezing point depression calculations and molarity is used for osmotic pressure calculations?
Molality is independent of temperature, so when you are trying to find changes in boiling and freezing points you need something that will stay constant regardless of the change in temperature. Molarity is temperature dependent and also is based on the volume of a solution, both of which are needed to calculate pressure using the ideal gas law, PV=nRT. Osmotic pressure is similar but we substitute the number of moles of the solution and the volume by using the molarity, you cannot do this with molality, since it is dependent on mass, not volume.
Compare the boiling and freezing points of 1m solution of glucose to a 1m solution of Cacl2. Why does CaCl2 have a higher boiling and a lower freezing Please explain not just say its 1m and then 3m?
Boiling and freezing points are colligative properties, meaning they depend on the number of solute particles dissolve in solution. Glucose is a molecular compound so it is one particle dissolved in solution. CaCl2 will dissociate into three particles in solution. There are three times as many particles present in solution when CaCl2 dissolves.
Explain why the water froze at a temperature lower than 0 degrees Celsius ?
Pure water, at normal atmospheric pressure freezes at 0 deg C. If the pressure is greater than normal atmospheric pressure (760mm of Hg) or if the water contains dissolved substances, its freezing point will be below 0 deg C.

Henry's law states that, the partial pressure of the gas in vapour phase is proportional to the mole fraction of the gas in the solution.
