Baking soda is a solid, therefore it will not evaporate even when mixed with water. The water will evaporate and leave the baking soda behind.
salt has to break down first
Adding vinegar to water the effect of boiling point elevation occur.
Salt changes the molecular composition of the water, causing its boiling point to go up. That's why it takes it longer to boil.

Water with oil boils faster than plain water because the presence of oil reduces the surface tension of water, allowing bubbles to form more easily. These bubbles help the water heat more quickly and reach its boiling point faster.
For salt water to boil faster than plain water, the salt concentration would have to be fairly high. In addition, the salt water would need to be a salt water solution before putting the pot on to heat because of the density of the water content itself.
A liquid boils when the vapor pressure of the liquid is equal to the atmospheric pressure. The presence of salt in the water reduces the vapor pressure of the water at the temperature at which plain or distilled water will boil. Since the temperature of the salt water must be higher to reach the same vapor pressure as the atmosphere, it takes longer to boil.
Adding salt to water actually increases its boiling point, so it will take longer for saltwater to boil compared to plain water. It is not recommended to add salt solely to make the water boil faster.
No, water that is covered does not boil faster. Covering the pot can actually trap heat and make the water boil slower.
A possible diagram could show two separate containers, one filled with plain water and the other with salt water, both being heated. Temperature measurements over time could be plotted on the diagram to show the rate of temperature increase for each type of water. This could help visualize and compare whether salt water boils faster than plain water.
Raises the temperature at which the water boilsAdding salt does not make the water boil faster, but makes the water boil at a higher temperature than 100 degrees Celsius. This may allow you to cook food in that water faster than in plain boiling water.
Salt (or anything dissolved into water) will increase the boiling point of water. It will take longer to come to a boil. Salt reduces the vapor pressure of the water and so requires a higher energy level to boil.
