Begin with 3 free Unit 15 practice problems. When you want more reps on pH, buffers, acids, bases, and titration ideas, premium unlocks Quick Sets of 3, Standard Sets of 9, and Extended Sets of 18 from this 81-problem bank.
3 Free Sample Problems
A strong place to begin: these 3 problems help you check whether the acid-base patterns are starting to feel more organized and usable in calculation problems.
#4Weak Acid pH
Calculate the pH of a 0.100 M acetic acid solution. (Ka = 1.8 × 10⁻⁵)
#5Conjugate Pairs
In the reaction HCO₃⁻ + H₂O ⇌ H₂CO₃ + OH⁻, which pair is a conjugate acid-base pair?
#6Titration
25.0 mL of 0.200 M NaOH is titrated with 0.100 M HCl. What volume (mL) of HCl is required to reach the equivalence point?
