Calculating pH and pOH worksheet W 335 Everett Community College Tutoring Center Student Support Services Program 1) What is the pH of a 0.0235 M HCl solution? 2) What is the pOH of a 0.0235 M HCl solution? 3) What is the pH of a 6.50 x 10-3 M KOH solution? (Hint: this is a basic solution – concentration is of OH-)

Solving for the pH of a 0.0020 M solution of NaOH: pOH = -log (0.0020) pOH = 2.70 pH = 14 – pOH pH = 11.30 Without buffer: pH = 11.30 Step 4: Solving for the pH of the buffer solution if 0.1000 M solutions of the weak acid and its conjugate base had been used and the same amount of NaOH had been added:

Worksheet: Acid base problems – AP level Problems 1 – 10 Problem #1: Calculate the pH of the solution that results when 40.0 mL of 0.100 M NH 3 is: a) Diluted with 20.0 mL of distilled water. b) Mixed with 20.0 mL of 0.200 M HCl solution.

KEY Chemistry: pH and pOH calculations Part 1: Fill in the missing information in the table below. pH [ H 3 O 1+] pOH [ OH1–] ACID or BASE? 3.78 1.66 x 10–4 M 10.22 6.03 x 10–11 M Acid 3.41 3.89 x 10–4 M 10.59 2.57 x 10–11 M Acid 8.81 1.55 x 10–9 M 5.19 6.46 x 10–6 M Base 8.69 2.04 x 10–9 M 5.31 4.88 x 10–6 M Base 8.46 3.47 x 10–9 M 5.54 2.88 x 10–6 M Base

Determine the pH of the solution. Since "x" represents the hydroxide ion concentration, we can convert it into pOH and than find the pH. pOH = -log(2.9 x 10-3) = 2.54 pH = 14 – 2.54 = 11.46 Top. Example: What would be the pH of a 0.200 M ammonium chloride solution?

Since we have the concentration of hydroxide ions, we can solve for the pOH of the solution. The question asks us to find the pH of the solution, so we will need to convert pOH to pH. To do so, we simply subtract the pOH from 14. The pH of the solution is 12.3. Because sodium hydroxide is a strong base, it makes sense that the pH is above 7.
