#### exists and is an alternate of .

At STP(Standard Temperature and pressure), the temperature is zero degrees Celsius(273 Kelvin) and the pressure is 1 atmosphere. At RTP(Room temperature and pressure), the temperature is 25 degrees Celsius(298 Kelvin) and the pressure is 1 atmosphere.

# What temperature is the standard temperature used to measure solubility?

Answer   The standard temperature used to measure solubility is 25 Â°C .  

# The solubility of a substance at a given temperature can be expressed as?

amount of solute per amount of solvent

yes

# How does temperature effect the solubility of a substance?

Generally, the higher the temperature, the more soluble the solute is.

Yes, they do.

# What is the difference between soluble insoluble substance?

the soluble substances dissolve in water where as the insoluble substances do not dissolve in water

# Are different substances equally soluble in water?

No, different substances are not equally soluble in water. Every solid compound we know of is more or less soluble in water. One good thing to help us measure the amount of wh

# How do you compare solubility between substances?

Solubility can be written as %m/m (mass in g per 100g), %m/v (mass in g per 100mL), %v/v (mL per 100mL), ppm (parts per million), ppb (parts per billion) etc. Solubility is al

# Do Different substances have different solubilities?

If you like dubstep, then sure.

# Can the solubility of two different substances be the same?

i suppose they could if they held each other in suspension.

# What happens to solubility of a substance when their is rise in temperature?

Generally, as temperature increases, solubility increases. There are a few cases where the opposite happens, though.

# How does the solubility of a substance change with a rise in temperature?

In general solubility increases with temperature. However, thereare exceptions for instance the solubility of Oxygen in waterdecreases with temperature.
