Construct models and/or animations to communicate the differences between strong, weak, concentrated and dilute acids and bases

Differences between concentrated and dilute acids

Concentrated AcidsDilute Acids
Have relatively large amount of solute dissolved in solventHave less amount of solute dissolved in solvent
Have higher Ka valueHave low Ka value
pH ranges from 1 – 3.5pH ranges from 4 – 7

Differences between weak and strong acids

Strong AcidsWeak Acids
Completely dissociate in water to produce H+Dissociate partially in aqueous solution
Have lower pH value (0 – 1)Have lower pH value (5 – 7)
Are mostly inorganic acids; Example: HCl, HNO3, H2SO4 etc.Are mostly organic acids; Example: HCOOH, CH3COOH etc.

Differences between concentrated and dilute bases

Concentrated BasesDilute Bases
Have relatively large amount of basic solute dissolved in solventHave less amount of solute dissolved in solvent
Have higher Kb valueHave low Kb value
pH ranges from 7 – 10pH ranges from 12 – 14

Differences between weak and strong bases

Strong BasesWeak Bases
Completely dissociate in water to produce OH-Dissociate partially in aqueous solution
pH ranges from 7.3 – 10pH ranges from 10 – 14
Have higher electrical conductivityHave lower electrical conductivity
Example: NaOH, KOH, Ca(OH)2 etc.Example: Hydrazine, alanine, dimethylamine etc.
