The line on the graph on The Chemistry Reference Table G indicates a saturated solution of NH4Cl has a concentration of 60. g NH4Cl/100. g H2O at 66 degrees celcius.

What is mean by saturated liquid and vapor?
Any addition of thermal energy to a saturated liquid will cause it to vaporize. Any subtraction of thermal energy from a saturated vapor will cause it to condense.

What are the factors that affect the products of a chemical equation?
temperature, pressure, concentration
What are three factors that affect solubility?
(1) Temperature (2) Nature of solute or solvent (3) and Pressure.
What is equilibrium vapor pressure?
It is vapor molecules in equilibrium with a liquid in a closed system exert a pressure proportional to the concentration of molecules in the vapor state.
What is mean saturated liquid and vapor?
A liquid or vapor is saturated when it is at the temperature and pressure where it would be in equilibrium with the other phase; saturated liquid at the boiling point or saturated vapor at the dew point. If the pressure is raised, the vapor will condense until the pressure is restored to the original pressure or all the vapor is condensed. If the pressure is dropped, a saturated liquid will boil until the pressure rises back to the original pressure or all the liquid has vaporized. If the temperature is increased, a saturated liquid will boil off completely unless the vaporized liquid raises the pressure enough to establish a new equilibrium. If the temperature is dropped, a saturated vapor will condense until the pressure has dropped enough to establish a new equilibrium.

What is meant by saturation temperature and saturation pressure?
The temperature and pressure of the atmosphere must be at that point or in an interval of values for the substance to be saturated. When mixing solutions, the temperature and pressure must be within a certain range for the substance to dissolve.
When is a liquid solution saturated?
When a compound become insoluble in a liquid at a given temperature and pressure a saturated solution is obtained; the limit of solubility is reached.

What the device used to increase the temperature of the saturated steam without increasing its pressure is called?
There is a small problem with the question: if you increase the temperature of saturated steam without increasing pressure, it will no longer be saturated - it will be superheated. With this in mind, it should be no surprise that the device that does this is normally called a "superheater". The picture accompanying this question is an example of a superheater.

What is ill-saturated vapour pressure of a liquid?
The vapour pressure of a substance is related to how fast it is evaporating. Vapour pressure varies directly with temperature. The hotter it is, the higher the vapour pressure. A substance boils when the vapour pressure of the liquid equals atmospheric pressure pushing down on the substance: usually taken to be 760 mm Hg or 101 kPa. If you know the vapour pressure of a substance you can estimate how much of that substance would be in air above the substance if you put it in a closed room and allowed it to equilibrate. This is called the saturated vapour concentration. If you know for instance that the lower flammable limit of the substance is 0.5% (1% = 10,000 ppm), you would be concerned about the potential for fire if the saturated vapour concentration was greater than 5000 ppm at room temperature. Without ventilation, there would be enough of the substance in air to ignite if there is a source of ignition. In a similar way, if the allowable exposure limit for the substance was an 8-hour time-weighted average of 500 ppm, you would know that it is possible to be overexposed to the substance by inhalation if the saturated vapour concentration exceeds 500 ppm. Estimate the saturated vapour concentration (SVC) using the following formula: SVC = [(vapour pressure of substance in mm Hg)/ 760 mm Hg] X 10^6 Ed Gatey BSc (Chem), CRSP, CIH
What dissolves soap but not salt?

What is the temperature of dry saturated steam at 510psig?
It will vary slightly with changes in atmospheric pressure, but is approximately 472ºF.
