ACIDS & BASES PRACTICE WORKSHEET

Remember that showing work is preferred.
ACIDS & BASES PRACTICE WORKSHEET
1. Calculate the pH of the following solutions and identify each of them as acidic or
basic:
+ -8 a) [H3O ] = 3.4x10 M
– –5 – –12 b) [OH ] = 1.8x10 M c) [OH ] = 6.5x10
+ M –4 d) [H3O ] = 2.6x10 M
+ -3 2. A solution of HBr has [H3O ] = 4.5 x 10 M. Calculate the pH of this solution. 3. Identify the Bronsted-Lowry acid and base conjugate pairs for each of the following
equations:
a) HNO3 + OH b) CH3NH2 + c) OH – – → – H2O + NO3 + H2O → CH3NH3
2– + HPO4 3– → H2O + PO4 + OH – 4. Complete the following table:
+ pH [OH ] –4 (a) 5.4x10 –10 (b)
(c) Acidic, basic, or
neutral? – [H3O ] 7.8x10
10.75 5. Rank the following solutions in order of increasing acidity (from lowest to highest):
– Solution A with pH = 6.50
+ –5 M Solution B with [H3O ] = 3.5x10 M < < Solution D with pH = 5.85 < least acidic most acidic 6. Complete the following table:
Acid
HS Conjugate base – ClO – 4 H3PO4
– HCO3 7. What is the pH of a solution prepared by dissolving 2.5 g HCl in water to make 425
mL of solution? 8. –10 Solution C with [OH ] = 6.0x10 27.8 mL of 0.156 M solution of HCl was used for the titration of 20 mL of a strong
base. Calculate the concentration of the base.
