Concentration Calculations

Concentration Calculations. Percent by Mass. Concentrated vs. Dilute. Concentrated means that a solution has a relatively large amount of solute. If you make a dilute solution of Kool-Aid, it will taste strong . Dilute means that a solution has a relatively small amount of solute.

extent to which the acid dissociates determines its strength

extent to which the acid dissociates determines its strength Polar water allows for acids to dissolve Strong Acid - Dissociates completely in a solvent Weak Acid - Releases few hydrogen ions in the solution. ** Lower the pH the stronger the acid**. Strength of Acids.
