Sodium bisulfite does not have a fixed freezing point as it is a mixture of sodium metabisulfite and sodium sulfite. The freezing point can vary depending on the composition of the solution. Generally, a solution of sodium bisulfite will freeze at a lower temperature than water due to its composition.
The maximal freezing point depression for sodium chloride is -18 0C. For the theoretical calculus see the link below.
Sodium metal freezes at 97.72 oC
Increasing the concentration of sodium chloride in water the freezing point is lower.
A 7 % sodium chloride solution in water has a freezing point of -4,38 0C.

No, adding NaCl to a solution will actually lower the freezing point of the solution. This is because the presence of dissolved ions from the salt disrupts the formation of ice crystals, causing the freezing point to decrease.
Dissolved solute (NaCl, salt) will raise the boiling point and lower the freezing point of water. This is known as a colligative property.
The nontoxic solute that requires the least concentration in volume to decrease the freezing point of water is sodium chloride (table salt). When dissolved, it dissociates into sodium and chloride ions, effectively lowering the freezing point through colligative properties. However, if considering a nontoxic option, sugar (sucrose) is often used, but it generally requires a higher concentration than sodium chloride to achieve the same freezing point depression. Thus, sodium chloride is typically more effective in smaller concentrations for this purpose.

The melting point of salt (sodium chloride) is the same as its freezing point, which is 801 degrees Celsius or 1474 degrees Fahrenheit. At this temperature, salt transitions from solid to liquid or vice versa.
The freezing point of sodium permanganate is 36 degrees Celsius. This is an inorganic compound that has the chemical formula of NaMnO4. Its molar mass is 141.9254 grams per mole.
