Acids, bases and pH
Main lesson
[H⁺] from pH
Use this for “A solution has a pH of 8.50. What is its [H⁺]?”
A strong base: pOH and pH
Use this for “A solution of 0.010 M NaOH: what are its pOH and pH?”
Titrating a strong acid
Use this for “25 mL of 0.1 M HCl is titrated with 0.2 M NaOH. Where is the equivalence point?”
Titrating a weak acid
Use this for “20 mL of 0.1 M acetic acid (Kₐ = 1.8 × 10⁻⁵) is titrated with 0.1 M NaOH.”
Acid, base or neutral?
Use this for “Is baking soda solution an acid, a base or neutral?”
