A solvent is the dissolving medium in a solution.
Waterin salt water
·Liquid in Solid-Liquid mixtures
·The larger amounts in liquid-liquid mixtures
·Liquid in gas-liquid mixtures
Water is the universal solvent!!!
What causes solute and solvent to become a solution?
Caused by the random molecular motion of the solvent
“Factors that Affect the Solution Process”
Pressure ( in gas and liquids)
·the ability of substance to dissolve
·amount of solute that can dissolve in 100g of water
Solids tend to dissolve best when:
· Ground into small particles
Gases tend to dissolve best when:
· The solution is cold
· Pressure is high
Nonpolar solutesdissolve best in nonpolar solvents
Polar and ionic solutesdissolve best in polar solvents
