Is the composition uniform?
Can it be chemically decomposed?
Can it be physically separated?
elements or compounds
Solutions, in chemistry, are homogeneous mixtures of two or more substances.
The substance present in largest quantity usually is called the solvent. The solvent can be either a liquid or a solid.
The substance that is present in smallest quantity is said to be dissolved and is called the solute. The solute can be either a gas, a liquid, or a solid.
Coke lists as its ingredients as: “carbonated water, high fructose corn syrup and/or sucrose, caramel color, phosphoric acid, natural flavors, caffeine”.
What is the solvent?
What are the solutes?
What can we classify CO2 as in carbonated beverages?
Ionic solid dissolving in water
Ni(s) + HCl(aq)
NiCl2(aq) + H2(g)
Oil is nonpolar while water is polar.
They are immiscible.
Generally, the solubility of solid solutes in liquid solvents increases with increasing temperature.
What amount of CaCl2 can be dissolved in 100 g H2O at 20° C?
ANSWER: 75 g CaCl2
Saturated or Unsaturated?
Increasing pressure above solution forces more gas to dissolve.
solubility decreases with increasing temperature
