What are volatile solutes?
A volatile solute (i.e., a solute that has a vapor pressure of its own) will contribute to the vapor pressure above a solution in which it is dissolved.
What are examples of volatile substances?
A volatile substance is one that evaporates or sublimates at room temperature or below. Volatile substances have higher vapor pressures versus non-volatile substances at the same temperature. Examples of volatile substances include alcohol, mercury, and gasoline.
What is the most volatile substance?
The table below shows some substances arranged in order of decreasing boiling point and increasing volatility. In the table, boron is the least volatile and hydrogen the most volatile substance.
What are non volatile solutes?
Nonvolatile means that the solute itself has little tendency to evaporate. Because some of the surface is now occupied by solute particles, there is less room for solvent molecules. The addition of a nonvolatile solute results in a lowering of the vapor pressure of the solvent.
What are volatile and non volatile acids?
Volatile acids are chemical compounds that undergo vaporization rapidly whereas nonvolatile acids are chemical compounds that cannot undergo vaporization rapidly. Thus, this is the key difference between volatile and nonvolatile acids.
Is Salt volatile?
Table salt. Sodium chloride (NaCl; table salt) is not volatile. It has a boiling point of 1413oC and does not evaporate readily even at elevated temperatures. It is not flammable or explosive.
Is h2so4 volatile?
(i) Concentrated sulphuric acid is a non-volatile acid.
Is acetone volatile?
Acetone (bp 56 oC) is more volatile (evaporates more readily) than water (bp 100 oC). It has a boiling point of 34.6oC and evaporates readily at room temperature. It is highly flammable and its vapors easily explode.
