Strong Acids

Strong Acids. Strong acids fully dissociate so: They are fully separated into their ions They are good conductors of electricity Are not in a state of equilibrium A 10x dilution results in pH increase of 1 React quickly as [H 3 O + ] is high Examples include: H 2 SO 4 , HNO 3 , HCl.

Titration Lab

Titration Lab. Weak Acid/Strong Base Example: 50.0 mL of 0.1000 M Acetic acid titrated against 0.1000 M NaOH. Initial pH (no OH -1 added). Here we will calculate pH using the K a and an I, ?, E table. We should expect an acidic pH, as no OH -1 has been added yet.

Questions

Questions. What is a strong acid? What is a weak acid? Write expression for pH HX ( aq ) + H 2 O (l) ? X - ( aq ) + H 3 O + For a strong acid like one above, what can you say about the concentration of [HX] and [ H 3 O + ]?. Water dissociation constant, K w. K w = [H 3 O + ] x [OH - ]
